Answer: B. Neurotransmitters; C. Enzyme components; E. Hormones
Explanation: Aminoacids have a variety of functions because they can create proteins.

In neurotransmitters, the glutamate appears to be related to functions of the brain, like learning and memory. Other functions of the aminoacids are regeneration of muscular cells, have a role in imunology, growth of tissue, production of collagen and others.
Answer:
D. A positive charge, because of a covalent bond with oxygen
Explanation:
A water molecule contain both hydrogen and oxygen atom. Water is a polar molecule because it has positive electric charge in one of it's poles and negative charge on the other. The hydrogen is positively charged and the oxygen is negatively charged which are bonded by covalent bond. Hydrogen is positively charged because it cannot attract electrons strongly like oxygen which is positively charged. There is unequal sharing of electrons in water molecules and this is why oxygen is slightly negative and hydrogen is slightly positive.
