Taxonomic Classification

Taxonomic Classification Taxonomic Classification Home›Science Posts›Taxonomic Classification Science PostsMicrobiology1. Microorganisms are the subject of the microbiological study that were first discovered by Antony van Leeuwenhoek (Totora, Funke, Case, 2012). They are the microscopic organisms classified into single- or many-celled ones according to their structure. Among the most widely spread examples, one can find archaea, bacteria, and protozoa. Although there is a great amount of examples of the microorganisms’ negative influence on human life, some other situations can show how they can bring benefits to the economy being used in production of yoghurt from Lactobacillus acidophilus, sauerkraut through cabbage fermentation and many other products. Rhizobium spp is used in agriculture for its abilities to transform atmospheric nitrogen to ammonia, thus improving the growth of plants. Some other microorganisms are used to produce antibiotics or other medicines.2. Taxonomy is “the science of classification of the living forms” (Totora et al., 2012). It is aimed at establishing the relations between groups and differentiating between them. Its history dated back to the Ancient Greece. The earliest history of the Western scientific taxonomy is associated with Aristotle, who has classified animals into with and without red blood ones (similarly to the distinction between vertebrates and invertebrates). Afterwards, vertebrates (with blood) were divided into live- and egg-bearing; and the invertebrates (without blood) comprised insects, crustacean, and mollusks. Since those times, the science was influenced by a number of scholars. Carl Linnaeus is considered to be the founder of the modern taxonomy.3. Five kingdoms of living things comprise Protista (that can be divided into Eubacteria and Archeobacteria), Fungi, Plantae, Animalia, and Monera. Protista mostly covers the single-celled eukaryotes and is presented by protozoa, protophyta, slime and water molds, etc. Fungi is presented by yeasts, molds, and mushrooms. Plantae comprises all green and flowering plants. Animalia is represented by all developed animals including vertebrates, mollusks, arthropods, annelids, sponges, and jellyfishes. Monera is the kingdom of unicellular prokaryotic organisms. 4. The scientific name for an organism based on Binomial Naming System is constructed using two terms. The first one denotes genus and the second one refers to species. For instance, in Homo sapiens, Homo erectus or Canis familiaris, the first words present genus and the second ones â€" species. Therefore, genus and species can be defined as the taxonomic ranks in the binominal scientific nomenclature that come one after another.Taxonomic ClassificationCnidaria and Porifera are the phyla in which the organisms lack organs. An example of Phylum Cnidaria is Jellyfish, which is radially symmetrical. Examples of organisms in Phylum Porifera include sponges and they lack symmetry on all axes (Luda ¨scher, 200 5).Phyla that show cephalisation include: Platyhelminthes and Echinodermata.Not all of them that have three germ layers. Organisms under Phylum Cnidaria have two germ layers, and organisms under Phylum Porifera do not have germ layers (Luda ¨scher, 2005).The Phylum Arthropoda has more species as compared to other Phyla. The species under Phylum Arthropoda include insects, crustaceans, and arachnids. For instance, the grasshopper, spider, beetles, butterfly, shrimps, and crabs (Luda ¨scher, 2005).There are two types of fish. They include the Cartilaginous or Chondrichthyes fishes and the bony or Osteichthyes fish. Cartilaginous or Chondrichthyes fishes, which are jawed and with paired nares, fins, two-chambered hearts, have scales, and the skeletons, are made of cartilage instead of bone. But they have bony teeth and do not have gill covers. Examples of fish under this group include sharks, skates, and rays. Another group is the bony fish also known as Osteichthyes. This group of fis h is the most common. The bony fish have bony skeleton and gill covers (Hairston, 1994).The monotremes, which are the egg-laying mammals, for instance the platypus. The Marsupials, which are the non-placental mammals, for instance the kangaroos. The marsupials have a pouch in which the young ones develop. The most advanced type of mammals is the placental mammals, for instance, the human beings. The young ones of the placental animals develop inside the placenta to a comparatively advanced stage (Gittleman, 2008).

Macbeth Soliloquy Log - 1005 Words

â€Å"Macbeth† Soliloquy Log 1.3.128 â€Å"Two truths are told†¦Ã¢â‚¬  The three witches have told Macbeth that he will be Thane of Cawdor as well as becoming king. Macbeth believes that the witches predictions will come true because he has just been announced the Thane of Cawdor. Macbeth is very confused. The tone of this soliloquy is one of bafflement. In fact, he proclaims that the witches’ fortune â€Å"cannot be ill, cannot be good† (130). Given that Macbeth had been told about being king, he’s had terrible thoughts about murdering Duncan which â€Å"unfix [his] hair† and â€Å"make [his] seated heart knock at [his] ribs† (135,136). Macbeth does not want to kill his friend, yet he still desires to become king. It is very ironic that his emotions and mind-set towards Duncan who is his â€Å"friend† has changed because of the fortune that the witches have given Macbeth. 1.7.1. â€Å"If it were done when ‘tis done† Macbeth and his wife are at their castle. Duncan has shown up for dinner as Macbeth has left to rethink the murder that Lady Macbeth has plotted for Duncan. Here Lady Macbeth adds that she wants to be a man because she scorns upon Macbeths lack of courage; she tells him he is â€Å"a coward. Lady Macbeth also says to him that her own lack of pity would expand to murdering her own child as it suckled at her breast. With this she admits that the milk of human kindness is absent in her.

Elderly Drivers - 1273 Words

An Age Old Problem In today’s society automobile accidents are an everyday occurrence. Mishaps can happen anywhere at any given time. In the past ten years accidents have averaged around ten million occurring for each year (US Census Bureau). That is 100 million automobile accidents in ten years. Most people would automatically point their fingers at young drivers in today’s world. A number of accidents are caused by teens though I believe a worse threat is starting to appear. This threat being elderly drivers over the age of 70. These elderly drivers could be considered dangerous due to their decline in sensory. With more elderly drivers increasing over the years, drivers everywhere could be in danger. Within the next 20 years the†¦show more content†¦Coordination allows th driver to stay on the road or in the proper lane without fail (Saison). The body is not the only thing to weaken with the aging process. The mind also begins to weaken and work much slower with time. With this it can become more difficult for an elderly person to pay attention to the road or notice caution signs. An example would be an elderly driver not realizing the car in front of them has stopped or slowed down thus resulting in crashing into the rear of the car. Reaction time also begins to fade with the mind (Saison). Reaction time is necessary in being able to make lane changes properly and prevent possible accidents. Having a diminished reaction time could result in an accident or car fatality. In order to keep drivers safe and out of harms’ way there is a simple solution. Make elderly drivers retake their driver’s education course to prove that they are able to drive properly. The drivers ed course isn’t simply there for one to get their license. The course teaches people of driving laws and how to properly operate their vehicle. It teaches individuals how to navigate the roads safely and prevent accidents from happening. In North Carolin a there are requirements that must be met before a person is allowed to drive. The first requirement that one must pass is an in class lesson and test.

Bronfenbrenner’s Analysis Free Essays

This paper analyzes and evaluates how Bronfenbrenner’s levels influenced my decision to attend graduate school and how they may impact career goals within my area of specialization. Bronfenbrenner develops a multi-level hierarchy of influences from the closest and most personal to the most abstract and societal. The purpose of my paper is to discuss, analyze, and evaluate Bronfenbrenner’s Ecological System Theory in relation to human development In the early 1970s’ Urie Bronfenbrenner developed an ecological theory of human development. We will write a custom essay sample on Bronfenbrenner’s Analysis or any similar topic only for you Order Now Bronfenbrenner’s book, â€Å"The Ecology of Human Development: Experiments by Nature and Design† (Bronfenbrenner, 1997) discusses in depth the ecological systems levels as the micro-meso-exo-macro- and the fifth system, the chrono-system layer. Bronfenbrenner summarized his theory utilizing concentric spheres in where the child begins his or her development in the center of the spheres. Comparing each sphere â€Å"†¦as a set of nested structures, each inside the next, like a set of Russian dolls† (Bronfenbrenner,1979. p. 3). Researchers found that a key factor in parent’s effectiveness was engaging in the child’s activities and environment. Darling (2007), asserts that â€Å"parental monitoring† of their children’s activities decreased the levels of behavioral problems and lead to â€Å"higher levels of adult approved activities† (Darling, 2007). Therefore, competence among children will â€Å"†¦depend on the quality of their environment† (Bronfenbrenner, 1999). Children from negative, deprived, disorganized backgrounds display more frequent and severe dysfunctional behavior in order to gain parental attention. On the other hand, parents providing attentive, stable and positive environments provide gratifying and positive reinforcement in aid of the children’s growth. Bronfenbrenner, 1999). Bronfenbrenner posited that â€Å"†¦the greatest effect on positive outcomes in environments with the greatest resources and for an individual who had the greatest ability to take advantage of those resources† (Darling, 2007). Microsystem Bronfenbrenner described his models as the m icro-system layer originating in the center of the sphere, involving the child’s interactions and activities within the context of family, school, daycare, and school, peer groups and how these interactions shape his or her development in a particular setting. A setting is where the child engages in â€Å"†¦particular activities in particular roles for particular times† (Bronfenbrenner,1979). For example, Bronfenbrenner observed parents emphasizing the importance of socially acceptable behaviors, exposed their child to positive activities, became involved in their child’s school, friends, thus producing children that were secure in new learning experiences. Mesosystem The mesosystem layer relates to the people in a child’s microsystem. It consists of the interactions between two or more settings which involve the developing child. For example, child’s parents and teachers may be interacting in discussions about the child’s progress. Bronfenbrenner found when parents take an active interest in the child’s early academic progress, that child has a greater chance of success upon entering high school (Oswalt, 2008). Exosystem The exosystem is comprised of the involvement and progression that takes place between the dyad setting, but it â€Å"†¦does not contain the developing child† (Bronfenbrenner, 1994). They are occurrences â€Å"that indirectly influence processes within the immediate setting in which the developing child lives† (Bronfenbrenner, 1994). For example, the child’s parents’ moving to a different state will directly affect the child’s interconnections with neighborhood friends and teachers. As an example, the child ‘knows’ he has lost his best friend, and may never find another. Thus, the child may meet this change with fear or dissatisfaction (Bronfenbrenner, 1994). The exosystem level includes the positive and negative structures found in the national government, cultural values, the economy, other macro influences. For example, Anglo-Saxon societies stress individual accomplishments, whereas Asian societies stress consensus and conformity. Cronosystem The chronosystem is the outermost shell that Bronfenbrenner displays. This is a temporal continuum that encompasses a person’s life experiences throughout their lives. A major example of the operation of this continuum is the impact of a parental death and the resulting behavioral change in the developing individual. The micro, meso, exo, and macro levels all impacted my individual development and career goals in obtaining a master’s degree in Human Services with a specialization in Social and Community Services. In the micro level, my earliest experiences were affected by the negative parental influences. As a child, I can remember my brothers and I were mainly spoken to when we did something wrong. In turn, these negative experiences affected my academic performance in school as well as my behavior. In the mesosystem, the only times my parents became involved in school were when they were called by the school principal to discuss my inappropriate behavior and my inattentiveness in learning. In the first grade, I was held back from entering the second grade because I could not speak English well or even Spanish. Again, this was a result of not having positive learning experience during childhood. It was not until the sixth grade that my principal decided I might succeed if I skipped the seventh grade to the eighth grade. That’s when my negative experiences turn to be positive and enlightening. I flourished that year and received a small scholarship to attend a school for girls. There I also flourished and began to have teachers and friends that were positive role-models. An example in the exosystem, I had a young brother with Down’s syndrome who at the age of 3 left our home to live in a state mental hospital. I was 13 years when my mother received a phone call from the hospital stating my brother had died from choking on some food. From that day on, my mother became distant and suffered from alcoholism. This experience saddened me greatly, but I was fortunate to have the support of my older sister, and wonderful teachers and friends that kept me succeeding in school. This success continued through college. However, when I was 16 years old, my mother was diagnosed with depression. Though I appeared happy with my school experience on the outside, inside, I felt depressed and longed for my mother’s love. All during this time, my father was physically present, but emotional absent due to the traumatic experiences at home. In the macro system, I grew up in a Hispanic culture, though my parents emigrated from Mexico to the US, my mother’s alien status became problematic as she could not speak English and inevitably could not take the test to become an American citizen. As a result, my mother felt she was a failure to herself and to my father who became a citizen at age 18. At the age of 47 years, I was able to complete my education at a women’s college. It was finally there I was fortunate to pursue my love of art. Upon graduation, I also found a new love of being of service to other’s less fortunate. I found that I obtained jobs not completely fulfilling, and when thinking upon this, I realized I could improve the possibility of reaching that fulfillment through graduate school to obtain an advanced degree in order to better serve the people I will work with. In conclusion, I don’t regret my experiences during my childhood. I learned a great deal about how one can attribute their success to resiliency. No matter how dismal matters were, there was always someone or something over the rainbow. I had a wonderful caring and nurturing older sister who loved me unconditionally. I had teachers who believed I was a worthwhile, intelligent and loving human being. With this nurturing, I was finally able to climb over the wall; only to look back at my stumbling blocks as experiences one takes to traverse their journey.

Why Leadership Essays - Leadership, Politics, Political Philosophy

Why Leadership Brian R. Newsom University of Charleston Why Leadership Since being in the Military for the past 18 years leadership is something that instilled in you since day one. While at boot camp where no one knows anything about what is going to happen next you are put in leadership roles as a squad leader or a guide amongst your peers. Their job is to ensure you are doing what is asked of you by the Drill Instructors and that task is carried out. They are working with you because they want to make sure the mission is accomplish and can answer any questions why it was done that way if the Drill Instructor ask. A good leader will work besides you, while a boss will tell you do something and new check up on you. Leadership is a behavior that all of us have inside us and can come out at any time. I like to think of myself as having great leadership skills because I will go out of my way to help out anyone I'm working with by showing them how to do and where they can improve their working habits to make their job a smooth easy process. Leadership o n different levels have different responsibilities but they all work toward the same outcome, to improve their working force and to have a safe and effective team. Some traits a good leader must have character, courage and compassion for the people they work with. If any leader does not have a good moral character which is something essential for a leader to have character because a leader needs to see what other cannot while working, the disadvantages that must be made, even if the sacrifice is their own. Another trait that a leader must have is courage and moral courage is a must because you need to be able to make decision that could be dangerous and harmful to your employees and you want someone that will make the right call if they think it is unsafe if even it cost the mission. No one's life is more important than fulfilling an order. The last trait is compassion, because you want to ensure your employees understand that you care for them and listen to their needs not just you r own. Leadership is something that is you earn with hard work and dedication.

Need For Federal Government Involvement In Educati Essays

Need For Federal Government Involvement In Educati Essays Need For Federal Government Involvement In Education The Need for Federal Government Involvement in Education Reform by____________ Political Science 2301 Federal and State Government OVERVIEW For centuries, generations of families have congregated in the same community or in the same general region of the country. Children grew up expecting to earn a living much like their fathers and mothers or other adults in their community. Any advanced skills they required beyond the three R's (Readin', Ritin' and Rithmatik) were determined by the local community and incorporated into the curriculum of the local schools. These advanced skills were taught to the up- and-coming generation so they could become a vital part of their community. The last several decades has greatly expanded the bounds of the community to almost anywhere in the country or anywhere in the world for that matter. Advances in transportation and communication has made the world a much smaller place then the world we knew as children. The skills our children need to realize parents' perpetual dream of their children having a better life are no longer limited to those seen in the local area. It is becoming more and more apparent that the education system of yesterday cannot adequately prepare students for life and work in the 21st Century. These concerns have prompted people across the country to take a hard look at our education system and to organize their efforts to chance the education system as we know it. WHAT'S HAPPENING OUT THERE? There are two major movements in recent years whose focus is to enhance the education of future generations. The Standards movement focuses on educational content and raising the standards of traditional teaching and measurement means and methods. The Outcome Based Education (OBE) movement is exploring new ways of designing education and changing the way we measure the effectiveness of education by focusing on results or outcomes. STANDARDS MOVEMENT In September 1989, President Bush and the nation's governors called an Education Summit in Charlottesville, Virginia. At this summit, President Bush and the nation s governors, including then-governor Bill Clinton, agreed on six broad goals for education to be reached by the year 2000. Two of those goals (3 and 4) related specifically to academic achievement: * Goal 3: By the year 2000, American students will leave grades 4, 8, and 12 having demonstrated competency in challenging subject matter including English, mathematics, science, history, and geography; and every school in America will ensure that all students learn to use their minds well, so they may be prepared for responsible citizenship, further learning, and productive employment in our modern economy. * Goal 4: By the year 2000, U.S. students will be first in the world in science and mathematics achievement. Soon after the summit, two groups were established to implement the new educational goals: the National Education Goals Panel (NEGP) and the National Council on Education Standards and Testing (NCEST). Together, these two groups were charged with addressing unprecedented questions regarding American education such as: What is the subject matter to be addressed? What types of assessments should be used? What standards of performance should be set? The summit and its aftermath engendered a flurry of activity from national subject matter organizations to establish standards in their respective areas. Many of these groups looked for guidance from the National Council of Teachers of Mathematics who publishing the Curriculum and Evaluation Standards for School Mathematics in 1989. The NCTM standards redefined the study of math so that topics and concepts would be introduced at an earlier age, and students would view math as a relevant problem-solving discipline rather than as a set of obscure formulas to be memorized. The National Science Teachers Association and the American Association for the Advancement of Science quickly launched independent attempts to identify standards in science. Efforts soon followed in the fields of civics, dance, theater, music, art, language arts, history, and social studies, to name a few. OUTCOME BASED EDUCATION MOVEMENT The decade of the 80s brought numerous education reforms, but few of them were a dramatic shift from what has gone on before. Outcome-based education (OBE) is one of those that is new, even revolutionary, and is now being promoted as the panacea for America's educational woes. This reform has been driven by educators in response to demands for greater accountability by taxpayers and as a vehicle for breaking with traditional ideas about how we teach our children. If implemented, this approach to curriculum development could change our schools more than any other reform proposal in the last thirty years. The focus of past and present curriculum has been on content, on the knowledge

Implicit Parameters in Java

Implicit Parameters in Java The implicit parameter in Java is the object that the method belongs to. Its passed by specifying the reference or variable of the object before the name of the method.  An implicit parameter is opposite to an  explicit  parameter, which is passed when specifying the parameter in the parenthesis of a method call. If a parameter isnt explicitly defined, the parameter is considered implicit. Explicit Method Example When your program calls a method of an object, its common to pass a value to the method. For example, here, the object Employee has a method called setJobTitle: Employee dave new Employee(); dave.setJobTitle(Candlestick Maker); The String Candlestick Maker is an explicit parameter being passed to the setJobTitle method. Implicit Method Example However, there is another parameter in the method call that is known as the implicit parameter. The implicit parameter is the object the method belongs to. In the above example, its dave, the object of type Employee. Implicit parameters are not defined within a method declaration because they are implied by the class the method is in: public class Employee {  Ã‚  public void setJobTitle(String jobTitle)  Ã‚  {  Ã‚  Ã‚  Ã‚  this.jobTitle jobTitle;  Ã‚  } } In order to call the setJobTitle method, there must be an object of type Employee.
