Questions and Answers

What is the primary advantage of the green stick insects in the green environment?

  • They have a greater ability to adapt to other environments.
  • They are more visible to predators.
  • They have an increased chance of survival and reproduction. (correct)
  • They are more likely to detect predators.

    • What is the relationship between the stick insects' body color and their survival in the different environments?

  • The stick insects' body color is irrelevant to their survival.
  • The body color has no impact on the survival of the stick insects.
  • The stick insects with a body color that matches their environment are more likely to survive. (correct)
  • The stick insects with a body color that does not match their environment are more likely to survive.

    • What can be inferred about the population of stick insects in the yellow-green environment?

  • The population will eventually become entirely yellow-green.
  • The frequency of the brown allele will remain constant.
  • There will be a decrease in the frequency of the yellow-green allele. (correct)
  • There will be an increase in the frequency of the green allele.
