<span>Since water is generally shallow, photosynthetic processes are possible for marine life which attracts more organisms to their primary food sources. Since the land is near shallow waters, discharges of nutrients from the soil are brought into the sea for the consumption of organisms. Aside from these reasons, periodic upwellings in the sea also provide cool and nutrient rich waters for different species.</span>

A. It can contaminate groundwater.
B. It uses a renewable resource.

Explanation:
Answer:
When many molecules of a simple compound join together, the product is termed a polymer and the process polymerization. The simple compounds whose molecules join together to form the polymers are called monomers. The polymer is a chain of atoms, providing a backbone, to which atoms or groups of atoms are joined.
Answer:
Primary active transport directly uses a source of chemical energy (e.g., ATP) to move molecules across a membrane against their gradient.
Answer:
add a water molecule to break bonds.
Explanation:
Fat digestion occurs in the small intestine where pH is alkaline. Protein digestion starts in the stomach at acidic pH but is completed in small intestine under the conditions of alkaline pH. Both processes use water molecules to break the covalent bonds of the nutrients. Peptidases present in small intestine add water molecules to the peptide bonds that join two amino acids together. This releases the individual amino acids from peptides. Similarly, the enzyme lipase adds water molecules to break the covalent bonds between fatty acids and glycerol of lipid droplets.
