the answer is " POPULATION".
Explanation:
A population is a group of individuals of same species living and inhabiting the same environment. in other words : All the inhabitants of a particular space forms a population in which the species interbreed.
so the correct answer is POPULATION.
The answer is letter C. ATP.
<span>
ATP stands for Adenosine Triphosphate which is present in every cell’s
cytoplasm and nucleoplasm which is essential in all the physiological
mechanisms. It is considered as the energy currency of life or the “molecular
unit of currency”. It stores the energy
that we need every day to do our daily undertakings. The primary function of
ATP is to transport chemical energy within the body cells for metabolism. It is
said that 1 moleculte of ATP is composed of 3 phosphate groups.</span>

In cell signalling, after a signal is sent, signal molecules bind to receptors on target cells and some activity in a target cell changes.
There are three stages in cell signalling :
1. The process of reception occurs when a signalling molecule from the extracellular environment is recognized by a cell. The chemical signal, which is also known as a ligand, is recognized as a signal when it attaches to a receptor protein either on the exterior of the cell or on the interior of the cell.
2. Transduction: This process occurs when the signalling molecule interacts with the receptor, which causes a change in the protein that makes up the receptor. The process of transduction is kicked off by this modification. In most cases, signal transduction occurs through a pathway that consists of numerous stages. The signal transduction route contains relay molecules, each of which influences the subsequent molecule in the pathway.
3. Reaction: In the third and last step, the signal causes a certain cellular response.
