QUESTION 8 Morphological differences are abundant among many species. We make assumptions about why adaptations exist, but to understand whether a specific trait is a adaptive and why, researchers must create experiments that have all the following, EXCEPT: a. replication of each treatment to ensure reliability of results. b. hypotheses that are testable and falsifiable. c. include control groups. d. exceedingly small sample sizes in each treatment group. e. experimental design that enables all full interpretation of differences.
Question 4. According to the core-satellite hypothesis, ______________. A) most species are common. B) abundance and occurrence are linearly related. C) satellite species are found in many sites surrounding core sites. D) core species are found at few sites.
QUESTION 22 Tiktaalik and Archaeopteryx are very important transitional forms. They provide evidence for evolution through examples of: a. microevolution b. macroevolution c. migration d. speciation
Question 1. In total, how many plant populations were established in this experiment? In each of these populations, what was the initial frequency of each plant genotype? Question 2. Did evolution occur in the control populations? If so, what factor or factors may have caused evolution by natural selection in these populations? Explain your answer. Question 3. Did evolution occur in the populations exposed to the generalist herbivore? If so, what factor or factors may have caused evolution by natural selection in these populations? Explain your answer. Question 4. Compare results for the control and generalist herbivore treatments. Why do you think the experiment showed the results that it did? Plant Genotypes Suppose the researchers conduct another experiment to investigate whether a generalist herbivore can affect the natural selection of a plant species. They establish ten replicate populations of the plant and expose each to two experimental treatments: a control (no herbivore) and…

QUESTION 14 Darwin’s finches on the Galapagos Islands are a group of species of finches. One of the major features noted is the variation in beak depth. We spent some time talking about the variation in the ground finch population and how that changed overtime and how that change corresponded to changes in environmental conditions, which affected food item characteristics and abundance. The changes in beak depth over time is a result of… a. natural selection b. gene flow c. sexual selection d. artificial selection
QUESTION 46 Which of the following statements about speciation is correct? a. Natural selection chooses the reproductive barriers for populations b. It always takes millions of years for speciation to occur c. The goal of natural selection is speciation d. Speciation is a process in which members become reproductively isolated into their own group.
