Carbon dioxide to trap the sun’s heat inside the atmosphere. what might happen to temperatures on earth if your prediction is true?

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.

Give three examples of plant activities that are affected by circadian rhythms and natural fluctuations in the length of daylight?

This is an active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient
