An experiment was designed to compare lengths of time that four
different drugs provided pain relief following surgery. The results
(in hours) are shown the table below
DRUG
A B C D
12 16 8 14
14 16 10 14
11 14 10 12
12 14 10
is there enough evidence to reject the null hypothesis that there is no significant
in lengths of pain relief for the four drugs at
alpha= 0.05

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.
