Enzymes are very effective in fastening up biochemical reactions. They can catalyze up to several million responses per second. As a result to which, the variation in speeds of biochemical reactions with and without enzymes may be immense. A normal biochemical reaction possibly take hours or regular days to happen under typical cellular conditions without an enzyme, but fewer than a
Answer and Explanation:

Acquired characteristics do not cause any alteration whatsoever in the hereditary information contained in the chromosomes. This theory is therefore not valid.
What are the functions of the cells resulting from a double fertilization event? Both cells go on to form embryos.

One cell goes on to form an embryo; the other cell goes on to form a fleshy fruit that has a protective function.
