Choose the best explanation of the difference between evolution and natural selection. Question 7 options: A) Evolution is the i
Bess [88]

The correct option here would be A. Evolution has to do with species changing over time while natural selection is a process that leads to evolution.

<h3>Evolution and natural selection</h3>

Evolution refers to the gradual changes to the morphological and or physiological characteristics of living organisms over time as a result of constantly trying to adjust to their environments.

Natural selection, on the other hand, refers to one of the processes through which evolution takes place. It refers to forces that select for or against traits in organisms.

What would be a consequence of a person having na levels in the blood and interstitial fluids that are well below normal?
Vladimir79 [104]

Consequence of a person having Na levels in the blood and interstitial fluids is that Neurons would not be able to undergo normal action potentials.

Nausea and vomiting. Lethargy, or low energy. Headache and confusion. Mental status changes. Normal motion capacity reaching the end of the axon. while an movement potential reaches the quit of an axon, vesicles fuse with the plasma membrane and launch neurotransmitter into the synaptic cleft.

At the peak of the action capability, two methods occur concurrently. First, a number of the voltage-gated sodium channels begin to near. 2d, many more potassium channels open, allowing wonderful fees to depart the mobile. Neurotransmitter is released from nerve ending when something must be excited or inspired , however when the task is carried out the neurotransmitter needs to be eliminated, otherwise the receptor may be in continuous nation of excitation which can be harmful.

Disclaimer:- Your question is incomplete, please refer below for complete question

What would be a consequence of a person having Na+ levels in the blood and interstitial fluids that are well below normal?

A) Neurons would all be depolarized.

B) Neurons would not be able to undergo normal action potentials.

C) Action potentials would occur with greater frequency.

D) Neurons would remain refractory following closure of voltage-gated sodium channels.

E) K+ channels would open to compensate for changes in membrane potential.

Hence the answer is option B Neurons would not be able to undergo normal action potentials.
