Answer:
The post-transcriptional modifications in the mRNA produced as a result of the transcription in eukaryotes provide many advantages to the mRNA.
The two post-transcriptional modifications are the addition of 7-methylguanosine cap at 5' end of mRNA called capping whereas the addition of the poly(Adenyl) tail at 3' end called tailing.
The advantages of capping are:
1. Protection of nascent mRNA from the degradation.
2. Recognition by transcription factors helps in translation.
The advantages of tailing are:
1. Protection of the mRNA from enzymatic degradation in the cytosol.
2. Transcription termination
3. Export of the mRNA from the nucleus
<span>Messenger RNA (mRNA) molecules are long strands of RNA nucleotides that directribosomes to make proteins. They travel from the nucleus to the ribosome. Ribosomal RNA (rRNA) molecules make up part of the ribosomes of the cell in the cytoplasm. Transfer RNA (tRNA) molecules transport amino acids to the ribosomes.</span>
Option (A) Torpor is the correct answer
Organisms that undergo hibernation have the ability to slow down their metabolism so as to lower the core temperature. This process is known as Torpor.
<h3>Why is torpor important for organisms undergoing hibernation?</h3>
Torpor is a state in animals where they lower all their metabolic activities and bodily functions so as to keep the body temperature low.
It is done by the animals to conserve resources in conditions where scarcity of food is there.
Some birds undergo torpor to conserve fat in the body.
Some animals use this technique of torpor to survive competition with other species.
These organisms come back to normal physiology when the conditions become favorable.

Answer:
When they grow bigger or there are some differences that haven't been there before? (Ex. Spots, stripes, Longer tusks)
Explanation:
I'm just thinking of this logically ok so don't know if this is correct but hope this helps.
