Explanation:

Great white sharks are blue-gray on the dorsal, or top, part of their bodies. This helps them blend in with the bottom of the ocean when viewed from above. The belly, or ventral, part of the body, is white. This makes it difficult to see the sharks from below, with sunlight shining in around them.

Cells are made up of organelles and the organelles present in a cell differ in animals cells and plant cells.

A feature that animals cells have which plant cell do not have is the presence of centrioles.

Features that plant cell have which animals cells do not have are the presence of chloroplast ,vacuole and cell walls.

Animals do not produce their food but plants do.Green Plants produce their food through chloroplast,which contains chlorophyll.

Plants has cells walls which is rigid and made up of cellulose,lignin and pectin.this rigid structure of the cell wall contributes to the rigidity of plants stems and roots.

Option A is incorrect because plant and animal cells have mitochondria.

Option B is incorrect because plants cells have both plasma membrane and cell walls.the cell wall surrounds the plasma membrane.

Serga [27]

Answer:

DNA ⇄ RNA → PROTEINS.

Explanation:

Central dogma explains the flow of genetic information of the living organism. The DNA is converted to RNA by transcription and further into protein product by the process of translation. DNA can increase its number by replication process.

Retroviruses do not follow the central dogma and they have the ability to convert the RNA into the DNA molecule by the enzyme reverse transcriptase. Their central dogma is as follows:

DNA ⇄ RNA → PROTEINS.

Thus, the answer is DNA ⇄ RNA → PROTEINS.
