AP Biology is a serious course with a number course goals. James Mitchell Crow explains. Binary fission is a method of asexual reproduction involving the splitting of the parent organism into two separate organisms.
This is my first year teaching biology abroad in Bulgaria and first year teaching IB I have taught biology before, but a quite different curriculum with a different set of resources. The expertise of the faculty represent the breadth of life science which will prepare you to enter the field after completing your associates degree or for transfer to a four year degree program. Course Description: A comprehensive introduction to living systems, including the scientific basis of biology, cell structure and function, genetic mechanisms, human anatomy and physiology, and ecological and evolutionary processes.

Learn biology 2 with free interactive flashcards. The stress is definitely not helping. The Biology Subject Test assesses your understanding of the major concepts of biology typically learned in high school and is an excellent way to showcase your achievements. What about electron orbitals, the. This is just as true of biology as it is of physics and chemistry -- college biology is an experimental science, not a descriptive science. Biology Form 2 Revision Questions.
From single-celled, certain organisms eventually evolved into the more complex multicellular forms.
Open Notebook Science. Hence, the biology major may cover several key areas. An integrated course stressing the principles of biology. You will have to read all the given answers and click over the correct answer. A single cell may be a complete organism in itself, such as a bacterium, or it may acquire a specialized function, becoming a building block of a multicellular organism.
Different catalysts are used to make polymers that possess different properties, with varying sizes of molecules, and in chains that may be linear, branched, or cross-linked. Long chains of 10, or more monomers can be packed closely to form a hard, tough plastic known as high-density polyethylene or HDPE, used for bottles containing milk, soft drinks, liquid soap, and other products.
On the other hand, shorter, branched chains of about ethylene monomers each produce a much less dense plastic, low-density polyethylene or LDPE. This is used for plastic food or garment bags, spray bottles, and so forth. There are other grades of plastic as well. In some forms of recycling, plastics of all varieties are melted down together to yield a cheap, low-grade product known as "plastic lumber," used in materials such as landscaping timbers, or in making park benches.
In order to achieve higher-grade recycled plastics, the materials need to be separated, and to facilitate this, recycling codes have been developed.

Many plastic materials sold today are stamped with a recycling code number between 1 and 6, identifying specific varieties of plastic. These can be melted or ground according to type at recycling centers, and reprocessed to make more plastics of the same grade. To meet the environmental challenges posed by plastics, polymer chemists continue to research new methods of recycling, and of using recycled plastic. One impediment to recycling, however, is the fact that most state and local governments do not make it convenient, for instance by arranging trash pickup for items that have been separated into plastic, paper, and glass products.
Though ideally private recycling centers would be preferable to government-operated recycling, few private companies have the financial resources to make recycling of plastics and other materials practical. Bortz, Alfred B. New York : Franklin Watts, Ebbing, Darrell D.

An atom or group of atoms whose presence identifies a specific family of compounds. When combined with hydrocarbons, various functional groups form hydrocarbonderivatives. A term referring to any compound that contains carbon, except for oxides such as carbon dioxide , or carbonates such as calcium carbonate i. Materials, usually organic, that can be caused to flow under certain conditions of heat and pressure, and thus to assume a desired shape when the pressure and temperature conditions are withdrawn.
Plastics are usually made up of polymers. Large, typically chain-like molecules composed of numerous smaller, repeating units known as monomers. Electrons that occupy the highest principal energy level in an atom.
