What is the defining feature of lipids?
O They are can be either polar or nonpolar, depending on the nitrogen-containing functional group attached.
O They are largely nonpolar because they consist of mostly non-polar C-C and C-H bonds.
O They are largely polar because they consist of mostly polar glycosidic bonds.

Answer:

O They are largely nonpolar because they consist of mostly non-polar C-C and C-H bonds.

Explanation:

Lipids do not contain nitrogen groups and do not have polar glycosidic bonds. In addition, the function of cellular membranes depend greatly on the fact that lipids (phospholipid bilayers) are polar!

The defining feature of lipids is- option. They are largely nonpolar because they consist of mostly non-polar C-C and C-H bonds.

Lipid is a micro biomolecule that is made up of fatty acids or their derivatives. These are molecules that are soluble in nonpolar solvents and insoluble in water.

Thus, the correct answer would be the option. They are largely nonpolar because they consist of mostly non-polar C-C and C-H bonds.

Most forms of vaccination consist of injecting a person with inactive viruses. How do the proteins from the inactive viruses protect the person from later infections by those viruses?

A. The proteins cause a mild infection that prevents the person’s body from responding to later infections.

B. The proteins bond with receptors on the cells of the person so that later active viruses cannot bind with them.

C. The proteins stimulate an immune response, which produces memory cells that can generate antibodies when new active viruses try to infect cells.

D. The proteins remain in the body and serve as a food source for later active viruses instead of feeding on the person’s tissues and causing the infection.
