Use this graph to answer part a and part b of this question. Select one of the criteria stated above and describe experimental evidence used to determine that DNA is the hereditary material. Describe the modern theory of evolution and discuss how it is supported by evidence from two of the following areas.
Describe how modern techniques of molecular biology could be used to determine whether the mutant allele is present in a given individual. These memory cells proliferate or differentiate faster when they attack the same antigen again.

Trace a molecule of O2 from the environment to a muscle cell in a vertebrate of your choice. The antigen recognizes the new skin as foreign. A a b c a B b Explain how these alleles are transmitted by the process of mitosis to daughter cells.
We will delve into these types later on Evolution is one of the major unifying themes of modern biology. What is the main difference between a humoral and a cell-mediated response? The antibodies make the antigens susceptible to phagocytosis by WBCs.
If the homozygous dominant condition were to become lethal, what would happen to the allelic and genotypic frequencies in the rabbit population after two generations? Identify THREE physiological or environmental variables that could cause the slugs to vary their distance from each other.
A new population was created by crossing 51 pure breeding homozygous dominant individuals with 49 pure breeding homozygous recessive individuals. Only T cells are infected resulting in a decrease of T cell population. A new population was created by crossing 51 pure breeding homozygous dominant individuals with 49 pure breeding homozygous individuals.
Discuss the structural adaptations that function in oxygen exchange between each of the following organisms and its environment: Respond to TWO and only two of the following: Explain how each variable could bring about the observed pattern of distribution.
The day was bright and sunny, and the wind was calm.EXPLAIN how the immune system achieves THREE of the following: provides an immediate nonspecific immune response.
activates T and B cells in response to an infection AP BIOLOGY EXAM ESSAY (FREE RESPONSE) QUESTIONS Author: Jerry W.

T. explain how the immune system attacks the transplant. Sample: 2C Score: 5 The student earned 3 points in part (a): 1 point for stating that the skin covers the body and blocks the entry of pathogens; 1 point for stating that mucus captures pathogens; and 1 point for stating that phagocytes engulf and kill pathogens.
AP essay questions AP Biology Essay Questions The following is a comprehensive list of essay questions that have been asked on past AP exams. Questions 1 and 2 are long free-response questions that require about 22 minutes each to answer and are worth 10 points each.
Questions 3–8 are short free-response questions that require about 6 minutes each to answer. Questions 3–5 are worth 4 points each and questions 6–8 are worth 3 points each. Read each question carefully and completely.
The antigen recognizes the new skin as foreign. Then it is rejected by the immune system. The antigens surface to the graft cells. Then they stimulate antibody production and T cell production. B Lymphocytes are turned into plasma cells which synthesizes antibodies. The antibodies circulate to the sites needed and precipitate antigens and/or complex.Download
