Which is an example of how the peripheral nervous system helps the body maintain its internal environment?
Lapatulllka [165]
The PNS helps to maintain internal balance, or "homeostasis," by the Parasympathetic division of the Autonomic Nervous System (ANS). Sometimes referred to as the "rest and digest" system, the Parasympathetics keep our internal activities regular throughout the day and night, such as a steady heart rate, slow breathing, digestion of food, filtration of blood, and excretion of wastes.

ICE Princess25 [194]

Answer:

The correct answer is - osmosis.

Explanation:

Paramecium lives in freshwater like the Potomac River which is hypotonic to the cytosol of the paramecium. Paramecium uses contractile vacuoles to transport the water from the lower concentration (outside of the cell) to a high concentration of solvent to the inside of the cells.

This process of cell transport is carried out by osmosis as their cytoplasm contains a higher concentration of solutes outside the cell. This excess water is collected into vacuoles called contractile vacuole that swells and finally internalized the water to the outside of the cell.

Thus, the correct answer is - osmosis.
