A researcher compares several species of maple tree by examining the amino acid sequence of a protein. The researcher discovers that the amino acid sequence differs in three locations depending on the species of tree. What can the researcher conclude based on this data? A. Maple trees are evolving rapidly. B. The different species have different morphological characteristics. C. The maple trees have been exposed to high levels of mutagens. D. The genetic makeup of the maple tree population has changed over time.
Why are humans so genetically similar within our species? A. Because humans evolved in multiple locations around the world at different times. B.

Because humans evolved in one location (Africa) and we haven't existed as a species for very long. D. Humans are not very genetically similar to one another.

Are gene mutations caused by selective pressures in the environment? In other words, do gene mutations arise in an organism out of need or want? Group of answer choices A. No, because gene mutations are not purely random. B. Yes, because gene mutations are not purely random. C. No, because gene mutations are purely random. D. Yes, because gene mutations are purely random.
Scientists are studying two populations of the same species of sea turtle. One population is quite small, with only 18 individuals, and the other is much larger, with 147 individuals. If a genetic factor such as a mutation were introduced to both populations at the same time, what could scientists predict about the impact?
The mutation rate is a. the likelihood that a new mutation will occur in a given gene. b. too low to substantially change allele frequencies in a population. c. lower for mutations that create beneficial alleles. d. All of the above are true of the mutation rate.
Which of the following most accurately describes mutations? a. They typically have immediate and impactful evolutionary effects on populations. b. They are required for all populations to evolve. c. They are always deleterious. d. They occur so infrequently that most populations to harbor very little variation.
Why did dark-colored rock pocket mice first appear in a population of light-colored rock pocket mice? Group of answer choices A.
