V (volume) = 5l
c (molar concentration or molarity) = 3 M = 1 mol/l
c = n/V, where n is the number of moles or amount of substance
So: n = c * V = 3 mol/l * 5l = 15 moles
Genetic engineering because the genes of the plants were modified
The answer is D: solar energy is a renewable source
<span>Amylase needs an optimum pH for its activity. It is in the range of 6-7. Below or above pH will denature this enzyme. The pH level is optimum for this enzyme in the mouth and hence it catalyses the break down of sugar. The pH level of stomach is lower than its optimum level duet to the activity of gastric acid. Hence the enzyme becomes inactive in the stomach.</span>
didnt understand the question, but the answer i think would be
The eukariotic cell cycle
