Urgent why is it necessary for dna to exist in its long, thread like form of chromatin during most of its life? a)dna must be spread out in order for the code to be read properly. b)chromatin conserves the nucleotides on the end of the strands from being destroyed. c)it is less energy intensive for the cell to remain in chromatin form. d)dna in chromatin form cannot be seen on a microscope.

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.
