4. What factors contribute to a random distribution pattern? Why do animals not maintain this distribution pattern year round?

Random distribution may result when resources are equally distributed and are not scarce. As breeding brings individuals together, random distribution is not maintained year round.

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

that would be b i just took the test : )
