Question

question 6
using your graphs and the data above, what explains the patterns you see between invaded and uninvaded islands?
select the two best answers.
□ a. the population of green anoles that changed in order to survive reproduced at a higher rate and passed on their traits.
□ b. the population of green anoles did not show change over time, because the invasion of the brown anoles did not cause any changes.
□ c. the green anoles on the invaded islands survived if they were able to climb and perch at higher heights. they could do this because they had larger footpads and more sticky scales on their feet.
□ d. the population of green anoles that survived and reproduced had a higher average footpad size and a larger number of sticky scales on their feet.
□ e. the green anoles that survived and reproduced had a smaller number of sticky scales on their feet and a lower average footpad size.
□ f. the green anoles on the invaded islands were able to grow larger footpads and sticky scales in order to climb and perch at higher heights and survive.

Explanation:

• Option A: This aligns with the concept of natural selection. Traits that help in survival (like those related to footpads and sticky scales) would be passed on if the individuals with those traits reproduce at a higher rate.
• Option C: It describes a survival mechanism. Green anoles on invaded islands having larger footpads and more sticky scales (traits) that allow them to climb higher (a behavior for survival) is a valid pattern explanation.
• Option D: This also ties in with natural selection. The survivors (with favorable traits - larger footpad size and more sticky scales) reproduce and pass on these traits.

Options B is incorrect as there is a change (as per the context of the question which is about patterns between invaded and uninvaded islands, implying change). Option E is wrong because it describes the opposite of what would be expected for survival (smaller footpads and fewer sticky scales are not likely to aid in survival when there is competition from brown anoles). Option F is incorrect because anoles don't "grow" these traits in response to the invasion in the way described; these are traits that are selected for through natural selection (already present in the population to some extent, not developed on - demand).

Answer:

A. The population of green anoles that changed in order to survive reproduced at a higher rate and passed on their traits.
C. The green anoles on the invaded islands survived if they were able to climb and perch at higher heights. They could do this because they had larger footpads and more sticky scales on their feet.
D. The population of green anoles that survived and reproduced had a higher average footpad size and a larger number of sticky scales on their feet.
