Ap Biology Assignment

What is the function of ribosomes? What are their two components? Ribosomes are the cellular components that carry out protein synthesis. Their two components are a large subunit and a small subunit.

11. Define the following: Genetic drift: unpredictable fluctuations in allele frequencies, reduces genetic variation over time through such losses of alleles

1. The anatomical region found between the lungs that extends from the sternum to the

K. Paraphrase the three potential fates of the excited electron produced when a photon meets a chlorophyll molecule

Biology 102 introduces students to the concept of evolution, the principles of evolution, natural selection, and major kingdoms of living things organisms. My major is nursing and taking this course is a prerequisite and is required for my major. Taking Biology courses will help me be better knowledgeable in my chosen field. I took biology 101 last semester and we learned about cell and organisms. These are fundamentals things that someone who plans to have a career in the healthcare field needs to know. Also these courses are prerequisites for other science courses I have to take such as microbiology, human anatomy and physiology. As a future nurse these are information that will come in handy everyday. I have three years left in my undergraduate study and more

3a. Body more than five times as long as broad; front edge of dorsal fin far

|(2 marks) | |c. |State two symptoms that may have led the veterinarian to suspect that George was suffering from a thyroid hormone |

3. State the name and structure of the functional group for each type of biologically

The final 2 property points were earned for the description and discussion of specific heat.

1) The layer of the GI tract wall that is responsible for motility is the

7)a) You would do the Benedict’s reagent test for simple sugars and the Lugol’s solution or Iodine test for polysaccharides and starch. To test the lipids you would use the Sudan iV test and Biurets reagent test for protein.

1. Information transfer is fundamental to all living organisms. For TWO of the following examples, explain in detail, how the transfer of information is accomplished.

1) Water molecule is formed with 2 hydrogens and one oxygen atom. Water molecule is a polar molecule because both the opposite side of the molecule have opposite charges. And also, atoms are linked by covalent bonds.

During the Light Dependent reaction, the suns energy is caught by the chlorophyll molecule, this happens as oxidation. Energy in the form of a photon is required to increase the energy levels of electrons which move out of the chlorophyll during oxidation. The energy must then be linked to the ADP reduction to ATP and coenzyme NADP+ which is condensed to NADPH + H+. This reaction requires light for it to take place, where it occurs on the thylakoid membranes. Energy from the light is converted into chemical energy. The molecules of chlorophyll are then attached to the thylakoid membranes, which can be attached with accessory pigments and different types of proteins to produce a photo system; in the middle of all photo systems there are different types of chlorophyll each one has a specialized task to absorb a certain wavelength of light. The Electrons inside of the chlorophyll absorb the energy produced by the photons and intensifies them so that they are excited. These excited electrons are easily detached from the chlorophyll in the form of oxidation.

Test the hypothesis: You cross the dwarf and tall plants and then self-cross the offspring. For best results, this is repeated with hundreds or even thousands of pea plants. What special precautions should be taken in the crosses and in growing the plants?
