Part d - relationship of allele behavior to meiosis during which part of meiosis (meiosis i or meiosis ii) do the two alleles of a gene separate? during which phase does the separation occur? state your answer as meiosis i or meiosis ii followed by a comma and the name of the phase (for example, if your answer is meiosis ii and metaphase, enter meiosis ii, metaphase).

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.

How do tides affect the organisms living in intertidal zones? a. no organisms live in intertidal zones due to the tumultuous environment. b. the mechanical forces of the waves keeps the organisms clean. c. only plants live in intertidal zones because the animals float away with the waves and never return. d. the mechanical forces of the waves can dislodge the organisms from their habitat.

Body systems are not completely independent they integrate and work together describe one example of the integration between body systems
