1.

D

Explanation:

One of the places where lipids are usually deposited as fats is in the dermis of the skin. The layer offers insulation and the animals adapted to cold regions usually have thick blubber. Excess glucose in the blood is converted to fats and stored in certain regions of the body and later used during starvation. The regions include around vital organs like heart and liver therefore also serving as a cushion for these organs.

2.

muscles; hair and fingernails

Explanation:

Proteins are usually the building block for most organisms. They are translated in ribosomes through mRNA that is sourced from the transcription of DNA. Muscle is specially made of proteins actin and myosin that allow for contraction of muscle to do work.  Fingernails and hair are also made of keratinocytes that have keratin proteins in them. Only the keratinocytes at the base of fingernails and hair are alive.

3.

activation energy

Explanation:

For a reaction to proceed spontaneously, its activation energy should be very low to allow the reactants to proceed to form new bonds with each other into new products. Enzymes lower this activation energy in otherwise reaction with higher activation energy, allowing them to occur spontaneously (otherwise they wouldn't do so naturally)

4.

nitrogen and phosphorus; nucleic acid

Explanation:

The phosphorus comes from the phosphate molecule that is attached to the 5’ carbon of the cyclic sugar. The nitrogen comes from the nitrogenous base that is attached to the 2’ carbon of the cyclic sugar. This combination forms the monomer that is called nucleic acid. The monomers combine in phospho-diester bonds to form chains referred to as DNA.
