Which piece of observation would support your explanation that the chameleon use a physical characteristic adaptation to survive in its environment?

The chameleon is able to change its color to blend with the surrounding environment.

Explanation:

The chameleon is able to utilize the camouflage adaptation to remain hidden against the predators and can also catch the prey. They are able to change their color from brown to green on grass and vice versa for tree trunk so that on blending with the color of the external environment chameleons remain undetected this is a kind of phenotypic advantage over other reptiles that help them to remain undetected by predators like birds, snakes, and others and help in their survival.

panem is a communist totalitarian dictatorship where all the resources and how they are allocated belongs to the capitol. the districts exist only to provide goods and services for the capital and most of the citizens live in poverty. it is a police state where the "peacekeepers" use force and threats to keep the people under control. dissent is outlawed and those who disobey the law are executed, flogged, or turned into avoxes. the games are another means in which the ruling elite in the capitol exert their power over the districts. when reading the books i drew parallels between panem and the soviet union and north korea. in no way is panem capitalist. the people in the capitol are wealthy but the majority of them are involved in the government somehow. it was the same way in the former soviet union where bigwigs in the communist party and high ranking government officials were given access to goods, services, medical treatments not available to the general public. if you think panem has a capitalist economy you need to brush up on your economics.
