The idea of crossing over or genetic variation occurs. please give this brainliest!
Answer AND Explanation:
Exponential phase is the phase during which growth is rapid. The growth rate is proportional to the amount of material or number of cells of the organism already present. This rapid growth is due to:
- An increase in number of cells dividing following a geometric progression.
- Cells having adjusted to the new environment.
- Food and other factors are not limiting hence cells are not competing for resources.
- The rate of cell increase being higher than the rate of cell death.
<span>Adaptation can help reduce competition for example if a species start feeding on other things. For example, if two species of squirrels fight for nuts, they can make sort of an animal non formal arrangement that one species eats from the trees and the other eats what falls on the ground, so they adapt to reduce competition.</span>
Answer:
The contractile vacuole acts as part of a protective mechanism that prevents the cell from absorbing too much water and possibly lysing (rupturing) through excessive internal pressure. The contractile vacuole, as its name suggests, expels water out of the cell by contracting.
