Study the table to see how stick insects of three different body colors survive in different environments. Which statements are supported by the data in the table? Choose three correct answers.
Stick insects actively choose to live in an environment where they are camouflaged.
Depending on the environment they live in, the green, brown, or yellow-green stick insects have an advantage over organisms that are easier to detect by predators.
Stick insects will be less likely to survive and reproduce if they are more visible to predators like the blue jays.
Depending on the environment they live in, the allele frequency for their body color may decrease or increase over time.
Stick insects will be more likely to survive and reproduce if they can avoid an environment that matches their body color.
