Answer:

True.

Explanation:

As we know, the plasma membrane of the cells is semi-impermeable, that is, it only allows the passage of some molecules in sizes and specific burning nature. Although the Na + and Cl- molecules are very small, they are polar, electrically charged molecules. These molecules are not well seen by the membrane, which does not allow them to pass into the intracellular medium.

A type of a balanced stretch involves targeting a specific muscle group. When stretching, a person should be aware of the agonist and antagonist muscles being stretched in able to create a balance between the joints where the muscles are attached. Stretching is an important phase in the exercise cycle and should not be missed as this prevents injuries in the joints and increases the blood flow into the muscles that were used during the activity. Stretching also contributes to lessening the lactic acid build up that happens during physical activity.</span>
