Answer to Question 2

Answer: Natural selection suggests that certain characteristics of an organism offer an advantage which allows the organism to reproduce and to pass on that characteristic to their offspring. The coloring of an organism may allow it to blend in to the background, thus escaping detection by predators. The capacity to remain still (i.e., freeze) may similarly allow an organism to avoid predation.
