Answer:

Because the biodiversity decreases.

Explanation:

An ecosystem is richer when it has a higher biodiversity, remember that each living thing has an specific role in the food web. When in an ecosystem this web is bigger, increases the probability of sustain a living thing. For example, in the sea, if there is a fish, this is going to be more probabilities of survive if this fish can eat different plants or other fish.

What are two reasons for why a species might disappear from the fossil record?
postnew [5]
1. One reason is extinctions happen because of some kind of change in the environment where a life form lives. While some species can adapt to the changes, others die, and if enough die, the species becomes extinct. These are some of the biggest factors in the extinctions of particular species. 2. Contaminants in the environment, such as pesticides.

Which of the following processes occurs in eukaryotic gene expression?RNA polymerase requires tRNA to elongate the molecule.mRNA
nignag [31]

Answer:

A cap is added to the 5 end of the mRNA

Explanation:

In prokaryotes, the translation process takes place simultaneously with the transcription but the mRNA molecule after synthesis undergoes some post-translation modification which protects the mRNA from the cytosolic environment.

One of these modifications is known as capping which refers to the addition of the cap at 5' end of the mRNA. This cap is added by an enzyme called guanyl transferease and protects the end of the mRNA.

Thus, the selected option is correct.
