They carry out every reaction happening within the body, hence they sustain life.
The charge of the electrical impulses sent from stimuli is extremely positive. Thus, the correct option is A. The net charge of such electrical impulses is positive because of the positively charged ions of the Na+.
<h3>What is an electrical impulse?</h3>
An electrical impulse may be defined as a nerve impulse that contains an electrical signal which travels throughout the body by the axon terminal.
In the resting potential state, the potential difference is -80mV, while after reaching the electrical impulse it changes to +40mV. This happens due to an electrical imbalance between sodium and potassium influx and efflux.
Therefore, the correct option is A.

Answer:
Signal transmission paths Learn how signals are transmitted within a cell from the cell membrane receptor. The chains of molecules that pass intracellular signals are known as intracellular signal transduction pathways.
The number of H+ ions moving down the channel.
So id say the answer is C.
<span>The answer is 0.74.</span>
This is
derived using the Hardy Weinburg principle of allelic frequency at equilibrium.
p + q
= 1
Therefore
if q = 0.26; then 1- 0.26 = 0.74
<span>In most occasions, the allele with the higher frequency
is usually the dominant one (but not
always). </span>
