Water plays an important role in solubility, transport, blood volume, blood pressure, and regulation of body temperature. Electrolytes help maintain fluid balance and assist with the generation of nerve impulses. Each of these contributions is essential for life and must remain in balance. Choose the correct statement about water and electrolytes. a. Water has a low heat capacity. b. After a muscle fiber is stimulated by a nerve signal, a release of stored calcium ions leads to muscle contraction. c. Sodium influx into a nerve cell leads to an increase in negative charge and depolarization. d. Water does not make a good solvent.

B

Explanation:

After a muscle fiber is stimulated by a nerve signal, a release of stored calcium ions leads to muscle contraction.

Common electrolytes include sodium, chloride, magnesium, calcium and potassium.

Sodium and potassium help in the generation of nerve impulses while calcium aids muscle contraction. Sodium is also actively involved in the movement across cell membranes.

The correct answer is B) After a muscle fiber is stimulated by a nerve signal, a release of stored calcium ions leads to muscle contraction.

Refer below.

Explanation:

Muscle contraction closes when calcium particles are siphoned once more into the sarcoplasmic reticulum, permitting the muscle cell to unwind. During incitement of the muscle cell, the engine neuron discharges the synapse acetylcholine, which at that point ties to a post-synaptic nicotinic acetylcholine receptor.
