Which statement about the genomes of prokaryotes is correct? Prokaryotic genomes are diploid throughout most of the cell cycle.
The prokaryotic chromosome is contained within a nucleoid, not nucleus.
Prokaryotic cells have more proteins than eukaryotes.
Prokaryotic chromosomes are sometimes called plasmids.

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.
