Answer:
All of the above
Explanation:
The ions present in our body can move through voltage gated ions channels present in the cell. The ions are unequally distributed in the interior and exterior of the cell.
The ion gated channel may get open or close depending upon the presence of the different ions. These ions movement changes the electric potential of the cell. The ions movement results in the propagation of the nerve impulse and may cause the cell membrane stretching. The binding of the molecules to the ion channels may open or close the movement of particular ions.
Thus, the correct answer is option (d).
The answer would be: <span>secondary aging.</span>
There is two type of aging, primary and secondary aging. Primary aging is the one that happens because of the age so it can't be prevented. Secondary aging happens because of bad diet and disease, so it can be prevented by doing healthy lifestyle or medicine.
Answer:
In the natural world, limiting factors like the availability of food, water, shelter and space can change the population of any living organism. Other limiting factors include:competition for resources, predation and disease can also impact populations.
Explanation:
Answer:
Calcium voltage gated ion channels
Explanation:
There are two types of ion channels involved in the neuromuscular junction and end plate potentials: voltage-gated ion channel (responsive to changes in membrane voltage which cause the voltage gated ion channel to open) and ligand-gated ion channel (responsive to certain molecules such as neurotransmitters).
The resting membrane potential of a motor neuron goes from -70mV to -50 with a higher concentration of sodium outside and a higher concentration of potassium inside. <em>When an action potential propagates down a nerve and reaches the axon terminal of the motor neuron, the change in membrane voltage causes the calcium voltage gated ion channels to open allowing for an influx of calcium ions. </em>These calcium ions cause the acetylcholine vesicles to release acetylcholine via exocytosis into the synaptic cleft.

Based on respiratory function tests, the correct options are:
- spirometer.
- vital capacity
- residual volume.
<h3>What is a respiratory function tests?</h3>
A respiratory function test is a test done to evaluate the ability of the lungs to take in air and remove carbon dioxide
The machine used for this test is called a spirometer.
Therefore;
- Ms. L's respiratory function was evaluate using a machine called a spirometer.
- The amount of air that can be expelled by maximum ex-halation after maximum inhalation is termed the vital capacity
- An increase in the amount of air remaining in her lungs after a normal expiration is called the residual volume.
