The problems of survival of animals on land are very different from those of survival of animals in an aquatic environment. Assume that the digestions occurred under appropriate conditions and went to completion. Explain the theory of evolution by natural selection as presented by Darwin.
Describe how the two populations may become different, including factors that can account for these differences. Explain the evolutionary mechanisms that can change the composition of the gene pool. Include in your discussion the factors that may contribute to the maintenance of genetic isolation.
Describe four problems associated with animal survival in terrestrial environments but not in aquatic environments. Unit 7 Evolution, Population Genetics, Speciation Paleontology provides fossils that reveal the prehistoric existence of extinct species. In addition, all living things share the same genetic code.
Sickle cell anemia and malaria 8. Describe how modern techniques of molecular biology could be used to determine whether the mutant allele is present in a given individual. Explain how DNA meets each of the three criteria stated above.
Biologists are interested in preserving the diversity of living organisms on the planet.
Charles Darwin proposed that evolution by natural selection was the basis for the differences that he saw in similar organisms as he traveled and collected specimens in South America and on the Galapagos Islands.
Ecological including seasonal isolation c. The arrows indicate reaction sites for two restriction enzymes enzyme X and enzyme Y. Explain how these alleles are distributed by the process of meiosis to gametes.
A portion of specific DNA molecule consists of the following sequence of nucleotide triplets.
Explain the evolutionary mechanisms that can change the composition of the gene pool. Explain the mechanisms that lead to evolutionary change. The fins and body shapes of sharks, penguins, and porpoises are analogous because they are adaptations to swimming. In most cases, neither parent of affected offspring has the condition.
How to Read a History Textbook A major difference between an Advanced Placement Program AP biology course and a regular high school biology course is the emphasis on detail. What would be the effect of a deletion or an addition in one of the DNA nucleotides? This provides strong evidence for the role of natural selection in evolution.
Include in your discussion the factors that may contribute to the maintenance of genetic isolation. Because anatomy may be modified for survival in specific environments, homologous structures may look different, but will resemble one another in pattern how they are put together.
Include in your answer a discussion of how the different types of RNA function in this process. Homologous structures are body parts that resemble one another in different species because they have evolved from a common ancestor.
The mechanism of action of restriction enzymes. As a result, changes in species and the formation of new species can be studied. Fossil deposits are often found among sediment layers, where the deepest fossils represent the oldest specimens.Questions 1 and 2 are long free-response questions that require about 22 minutes each to answer and are worth 10 points each.
