Two communities exist side-by-side on an island. Community A is characterized by a 4 species of birds with one predominant species out numbering the others significantly. Community B contains 4 species of birds each with enough individuals to maintain each population. After a drought of two years changes the ecosystem, which community has the highest probability of rebounding from this disaster?

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.

All individuals have two alleles for a given trait. according to mendel's these alleles are passed down one each from both mother and father.
