<span>The third option:</span><span>This statement is true because every step in protein synthesis requires enzymes, which are nothing but proteins.</span><span>
</span>I mean if you look at rRNA which is needed to make polypeptide chains, it is 2/3 protein, and then the helices, ss binding proteins, DNA polymerase and everything in transcription is protein.
So that last option/ third option is the best
<h2>
Answer: c. another action potential can be generated provided the stimulus is large enough.</h2>
Explanation:
Refractory period - (1) absolute refractory period and (2) Relative refractory period
.
Relative refractory period -It is the interval immediately following the Absolute Refractory period during this period, initiation of a second action potential is inhibited but not impossible. It is the period shortly after the firing of a nerve fiber when partial repolarization has occurred and only a greater than normal stimulus can stimulate a new response.
Macromolecules are also known as polymer molecules
because the world is spinning at a different angle and speed as it its orbiting the sun.
