Explanation:

Answer;

A.The internal organs are cushioned by fat.

Explanation;

-Most of the nutrients in food fall into three major groups: proteins, fats, and carbohydrates. The body uses fat as a fuel source, and fat is the major storage form of energy in the body.By supplying energy, fats save proteins from being used for energy and allow them to perform their more important role of building and repairing tissues.

Fat also has many other important functions in the body, and a moderate amount is needed in the diet for good health.They also cushion internal organs, provide insulation against temperature and also facilitate absorption of fat soluble vitamins.

The right answer is an isotonic solution.

An isotonic solution is a system in which the osmotic concentration is the same as the solute concentration of a cell. In this case, the cell does not swell or shrink because there is no gradient of water concentration across the cell membrane.

The water molecules diffuse across the plasma membrane in both directions, and the rate of water diffusion is the same in each direction of this cell without gaining or losing water.
