<span>Mitochondria and
chloroplasts are the result of the process called endosymbiosis. Mitochondria
and the chloroplasts are originally from the prokaryotes. They have the ability
to take up inside a large single cell organism which they help each other in
order to produce energy for each other. Endosymbiosis, from the term symbiosis,
the organisms that are symbiotic is living inside the other pair, just like how
the mitochondria and chloroplasts responds to each other.</span>
<span>Studying the changes in densities of pocket gophers when large herbivores such as elk are excluded from mountain forests would be an example of studying ecology at the community level.
A community refers to a group of organisms of various species that live in the same location and interact with each other. So, if this scientist is observing gophers and elks, they are looking at the level of communities, not anything more or less.

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
