Answer:
A. DNA repair
Explanation:
The p53 protein acts as a tumor remover by controlling a set of genes required for the cell division. This protein protects the genome by <u>restricting abnormal cells to proliferate</u> avoiding the replication of damaged DNA. The first resource the protein uses and prometes is DNA repair and if the DNA has irreparable damage, t<u>he last resource used by this protein is</u><u> apoptosis</u>.
When electromagnetic waves strike an obstacle, what usually happens is that part of the wave is absorbed by the obstacle, part is reflected back and part is transmitted through the material.
However, in case of a dark object; the dark object acts as a perfect absorber and absorbs all the electromagnetic waves.
So, the right answer is the diagram showing only absorption of the wave by the surface.
Well the endoplasmic reticulum has both smooth and rough bodies. Smooth is the synthesis of fats and detoxifies harmful bodies. Mostly in the liver. And the rough mainly synthesize proteins which are basic components of life. Proteins are sent all over the body and are used for many functions. The golgi is used to package those proteins and send those proteins through the body. Mitochondria creates energy and is the power house of the cell. And the plasma membrane is like the gate keeper. Decides what can enter it exit the cell and prevents harmful things from coming in. Allows proteins to leave.
Species evolve over time based on their environment.
If part of a group of a species gets isolated into a new environment, then both species (the initial environment and the new one) will evolve differently because of their different environments and in result become different.
So since they both evolve differently based on their different surroundings, the group that was isolated becomes a new species.
