Answer:

The phenotype of the moth changed due to natural selection. During the Industrial Revolution, objects in England became a lot darker in color due to the settling of coal pollutants in the air. These light colored moths did not have good camouflage in this environment. Therefore, most of the light colored moths did not survive to reproduce. However, the dark colored moths had better camouflage, and were therefore more likely to survive and reproduce. This lead to a shift towards darker color moths, as they had a higher survival rate than the light colored moths.

These two cells have several features in common. They also differ in several ways. The two cells share all but one feature liste
Kobotan [32]

Answer:

The correct answer would be B) enclosed in a protein capsule

Almost all living cells contain DNA as their genetic material. DNA control and coordinates the function of the cell. The two cells also must contain the DNA.

Cellular respiration refers to the set of biochemical reactions by which the cell generates ATP or energy. All the living cells produce energy through cellular respiration, however, they may utilize the aerobic or anaerobic form of respiration.

A ribosome is found in all the living cells including animal cells, plants, bacteria et cetera. They form the site for protein synthesis in all the cells.

The protein capsule is not a universal feature of all living cells. Thus, it may be present in one cell type and absent in another cell type.

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.
