Biology exam tests topics and skills discussed in your high school Advanced Placement Biology course.
If you score high enough, your AP Biology score could earn you college credit!
Describe the fluid-mosaic model of a plasma membrane. Include a description of mitosis and cytokinesis, and of the other phases of the cell cycle. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D.
Discuss the role of the membrane in the movement of materials through it by each of the following processes: 6. Indicate the ways in which a nonphotosynthetic prokaryotic cell would differ in structure from this generalized eukaryotic plant cell. Design an experiment, based on the principles of diffusion and osmosis, that the assistant could use to determine which of the flasks contains each of the four unknown solutions.
They require using information presented in the question to calculate an answer and enter it in a grid.
Answers can be in the form of integers, decimals, or fractions.Unlike the multiple-choice section, which is scored by a computer, the free-response section is graded by high school and college teachers.They have guidelines for awarding partial credit, so you may still receive partial points should you not correctly respond to every part of question in your essay.Describe each classical experiment and indicate how it provided evidence for the chemical nature of the gene. Discuss Mendel’s laws of segregation and independent assortment.Explain how the events of meiosis I account for the observations that led Mendel to formulate these laws. An organism is heterozygous at two genetic loci on different chromosomes.Unit 4 (Photosynthesis and Cellular Respiration) 10.Describe the similarities and differences between the biochemical pathways of aerobic respiration and photosynthesis in eukaryotic cells.Include in your answer (a) a description of how you would set up and perform the experiment: (b) the results you would expect from your experiments: and (c) an explanation of those results based on the principles involved.(Be sure to clearly state the principles addressed in your discussion.) 9. Choose THREE of the following four types of cellular transport.Explain how ATP is involved in each example you choose.Unit 5 (Meiosis, Mendelian Genetics, DNA Replication) 17.
