Answer:
- <u>Option:(1)-</u>The <u>Genetic drift </u>theory is an evolutionary concept that suggests that behaviors that help an organism survive are passed on while weak behaviors are lost.
Explanation:
According to this theory, an organisms faces different levels or kinds of environmental factors, which either suppresses or increases the level of a certain allele frequency inside an organisms genetic sequence, which then results in the change in behavior of that organism. And through many generations the changes in behavior may pass on from one to another, as the changes does not occur in a single generation.But, the alleles frequency are suppressed and increased with time, when they face different environmental factors or situations.
Adenosine triphosphate (also called ATP) is used by the cell as fuel to pump sodium out of the cell during the process of active transport. It carries energy to the areas of the body where it is needed. It is necessary for many of the cell's functions and is an important part of metabolism.
