I would say the answer is A
Answer:
Option-C
Explanation:
Action potential refers to the generation of electrical activity due to the influx and efflux of ions in the cell.
The cell which transmits the action potential is known as the neuron and the neuron maintains the membrane potential at -70 mv. The influx of sodium ions causes depolarization when it crosses the threshold value.
The generated action potential now travels in the neuron through its long tubular structure called an axon. The axon transmits the signal from the cell body towards the axon terminal and thus is known as the down the axon.
Thus, Option-C is the correct answer.
Same genus is more closely related. The farther down the list Phylum-Class-Order-Family-Genus-Species you go, the more closely related are the species in that taxon.
Answer:
Three factors are used.
The availability of sunlight.
The distance from shore and
The water depth.
Explanation:
<u>Availability of Sunlight
</u>
The photic zone is the upper part of the ocean into which sunlight penetrates.
<u>Distance from Shore
</u>
The intertidal zone is the strip of land where the land and ocean meet and overlap, or the zone between high and low tides.
The neritic zone is the marine-life zone that extends from the low-tide line out to the shelf break.
The oceanic zone is the marine-life zone beyond the continental shelf.
<u>Water Depth</u>
The pelagic zone is open zone of any depth. Animals in this zone swim or float freely.
The benthic zone is the marine-life zone that includes any sea-bottom surface regardless of its distance from shore.
The abyssal zone is a subdivision of the benthic zone characterized by extremely high pressures, low temperatures, low oxygen, few nutrients, and no sunlight
