Answer:

A hematocrit value of your blood would be greater than normal because of dehydration.

Explanation:

The hematocrit value is an indicator of the proportion of the solid components of blood (red blood cells) with respect to the liquid component (it means plasma). When you are severely dehydrated, the proportion of plasma diminish while the solid components remain the same. In consequence, the red blood cells concentration will be greater and the hematocrit value (solid components/plasma) will be higher than normal. This condition is reversible, if you drink enough water, your hematrocrit values will be normal again.

<h3>What is Nervous System?</h3>

According to biology's classical idea of the nervous system, an animal's nervous system is a highly sophisticated component that coordinates its movements and sensory data by sending and receiving signals from and to various regions of the body. In order to react to such occurrences, the nervous system and endocrine system collaborate to detect environmental changes that have an effect on the body.

Around 550–600 million years ago, worm-like invertebrates were the first to develop nervous tissue. The discovery of electrical impulses in plants and their utilization in recent decades, however, has called into question this conventional wisdom. These findings have led some researchers to suggest that plants have neural systems and that the science of plant neuroscience should be established.

The peripheral nervous system is involved in _____.
drek231 [11]

The peripheral nervous system is involved in both <u>voluntary and involuntary actions.</u>

Explanation:

The peripheral nervous system (PNS) is the neural system that resides outside the central nervous system (CNS). This contains nerves which in turn connect with the organs of the body like the sensory organs, glands, blood vessels, muscles etc with the central nervous system (CNS).

The PNS is divided into somatic and autonomic nervous systems.

The somatic nervous system contains sensory and motor nerve fibers which send sensory information and controls motor functions respectively. The voluntary movements of skin, skeletal muscles, bones, and joints are controlled by somatic PNS.

The autonomic nervous system composed of sympathetic, parasympathetic and enteric nervous systems controls the involuntary actions of smooth muscles of the internal visceral organs.

What ion movement changes the membrane potential in a contractile cell from negative to positive during the rapid depolarization
Lesechka [4]

Answer:

The influx of calcium ions.

Explanation:

The influx of calcium ions at a certain point produces phase of the action potential also called depolarization which results in the ion movement changes the membrane potential from negative to positive inside the cell.

In action potential, calcium ions may control gene transcription, cell excitability, and neurotransmitter release. In chemical synapses, the influx of calcium ions leads to vesicles filled with neurotransmitters move to the surface of the cell, and into the synaptic cleft release their contents.
