Answer:

A

Explanation:

It is believed that the moon was formed shortly (relative time) after the earth was newly formed. This occurred in a massive planet-sized collision that  ejected a huge chunk of the earth out into space. The chunk, still within earth gravitational reach, began orbiting the earth becoming the moon. Both earth and moon are slightly more than 4 billion years old.

torisob [31]

The sudden drop in blood pressure after a motor bike accident is due to the intensive loss of blood that reduces the blood volume of the body.

Blood is the red-colored fluid present inside the body and pumped by the heart. It consists of RBCs, WBCs and platelets. Its function is to transport oxygen carbon dioxide food, hormones from one part of the body to another through the RBCs. The red color of the blood is due to the pigment hemoglobin.

Blood pressure is the pressure with which the blood flows into the arteries of the body. It is of two types: systolic pressure and diastolic pressure. The ideal blood pressure must be approximately 120/80 mmHg.

olga nikolaevna [1]

Answer:

The gene cannot be transcribed and translated into a protein.

Explanation:

Turning off a gene means the gene cannot be transcribed and translated into a protein.

Turning off of genes is a form of gene regulation, a process that controls which genes are expressed or not expressed in a cell.

<u>The expression of genes requires that they are first transcribed from DNA to mRNA in the nucleus and then moved to cytoplasm where they are translated into proteins by the ribosome.</u>

Hence, a gene that will not be expressed has to be stopped from being transcribed amd translated by being turned off by the gene regulation process of the cell.
