Behavioral Observation: You are walking through the Costa Rican jungle and you see a bird trying to catch and eat a brown frog. Next to that brown frog is a bright red frog with blue legs that is ignored by the bird. You know that birds can see color so you are surprised that the bird would pick a more cryptic frog over the brightly colored frog. Please complete the scientific method. Research question: Why is the bird eating the brown frog but not the red and blue frog?

See the answer below.

Explanation:

The bird preferred to eat the brown frog instead of the red and blue frog because the red and blue colors serve as a warning to the bird. The bright color is a type of adaptive attribute known as warning coloration.

Most brightly colored preys are poisonous and bright the color is there as a reminder and a warning to potential predators. Hence, the predator bird in the illustration would rather eat the brown frog instead of the poisonous red and blue frog.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
