Recall from our classes on molecular evolution that some proteins evolve more rapidly than others. For example, the oxygen-carrying protein myoglobin evolves more quickly than the D1 protein of photosystem II. What explains this difference in the rate of protein evolution? A. Proteins like myoglobin have evolved more recently than proteins like D1 and thus have been forced to evolve more quickly. B. Changes to the sequence of some proteins can be tolerated as they don’t alter fitness; for other proteins, sequence changes are usually harmful. C. In constrained proteins like D1, evolution results primarily from nucleotide changes that alter the amino acid sequence of the protein. D. Protein evolution is dependent upon the rate of gene mutation and some genes have a higher rate of mutation than others.
7. According to evolutionists, which is the best test to show the relatedness of two organisms? * A. Similarity in development B. Similarity in courting behavior C. Similarity in structure D. Similarity in Genomic DNA
4. Why is the Hardy Weinberg law of equilibrium important to a study of evolutionary processes? a. it tells us how heavy are mammals and if they may have lived in cold enviroments in the past. b. It shows us to measure change in gene frequency in population to see if selection pressures are affecting gene expression. c.It allows us to study how eplgenetics affects specific traits d. It allow us to measure the age of fossils and date the origin of a species
