Which of the following macromolecules are a prominent part of animal tissues that function in insulation, animals conserve heat? carbohydrates lipids proteins nucleic acids

Option B = Lipids

Explanation:

Lipids include waxes, fats, steroids and oils. These are found in both eukaryotes and prokaryotes. Lipids play important role of energy storage, membrane formation, cell division and protection.

Structure of lipids:

Lipids are made up of triglyceride which are further consist of fatty acids and alcohol glycerol. Because of great diversity more than 10,000 lipids are discovered. Lipids are smaller than the protein.

Example:

Fatty acids are the lipids and act as a building blocks for other kind of lipids. The carboxyl group (-COOH) in fatty acids attached to the carbon chain trough attached hydrogen and make the chain water soluble. There are two kinds of fatty acids saturated and unsaturated. The saturated fatty acid has single bonds and unsaturated fatty acids have double bonds. The unsaturated fatty acids yield oils when combine with triglycerides.

Function of lipids:

Lipids play important role in organism. Some are important roles are given below:

1.They make protective barrier.

2.They take part in the formation of cell wall of plants and cell membrane.

3.They are also act as an energy storage device.

4.They take part in the formation of Golgi apparatus, nuclear envelop and other cellular compartments.

5.They provide the insulation against harsh environment to the vital organs

well we can't tell you because we cant see the time give a screen shot or something.

scientists have discovered that hiv does not cause aids by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. researchers from the gladstone institutes have revealed that hiv does not cause aids by the virus's
