Which organisms are not examples of an adaptive radiation?
gavmur [86]

Answer:

Option B, Mammals and reptiles in the post-dinosaur age.

Explanation:

Adaptive radiation is mechanism through which species evolve very fast from common single ancestors. In simple words two different species are said to have evolved through adaptive radiation when they have descended from a single lineage. This is not the case with mammals and reptiles.  

Generally in adaptive radiation, a species evolve when it faces new environmental challenges due to change of habitat or area. For example mammals have evolved from dinosaurs.  

Hence, option B is correct

What happens to mRNA after it completes transcription?
Nana76 [90]

The correct answer is "C."

mRNA stands for messenger Ribonucleic acid.  The role of mRNA is to carry genetic information for the synthesis of protein from the nucleus after transcription.

After the transcription process is over, the mRNA leaves the nucleus and heads to the ribosomes in the cytoplasm where translation of this information takes place.

The ribosomes are the work bench of the cell. They receive the mRNA with its coded information, read it and translate it and with the help of tRNA (transfer RNA), amino acids are fetched from the cytoplasm and linked together to form the exact protein that was coded for on the mRNA.
