Answer:
A. is increasing
Explanation:
The phrase "these days" tells us that we want something in the present. If it wanted the past, it would say "in those days" or something similar. So we can cross out d and b, because they are past tense.
It can't be c, because the subject-verb agreement is wrong (it would be increases, not increase).
We can conclude that the answer is a, <u>The population of the world these days </u><u>is increasing</u><u> very fast.</u> It's currently increasing.

Your ability to expend energy is very much dependent on the energy you have stored, and your cells’ ability to discharge it on demand. <span>A well functioning body will have a much greater ability to store and discharge energy. It will be able to work a lot longer before it becomes exhausted and before it needs to rest.</span>
Answer:
3 The mRNA was not bound to by a ribosome 4 tRNA: anticodon matching 5 switching from normal nucleotide for an abnormal one .
Explanation:
3 If the mRNA is not bound to the ribosome then this do not prevent the mRNA from being transported to the Endplasmic reticulum in the cytoplasm.This because binding of ribosome to the mRNA is essential after the mRNA has reached the cytoplasm to initiate the process of protein synthesis.
4 tRNA contains Anticodons that interact with the codon present in the mRNA to bring an amino acid specific for that codon to the A site of ribosome.
5 Mutation at the 3" nucleotide reading frame switch a normal nucleotide for an abnormal one.
