Explanation:
Positive feedback loops are rarer than negative ones because of homeostasis, but they do occur. Negative feedback loops return to the set point in reverse, and positive feedback loops amplify a departure from the set point.
Because the moon is rotating on its own axis and orbiting around the earth at the same time.
In populations of all living things, there is a variation of different traits. This is important for the process of evolution and natural selection because if the individuals in the population vary in size, shape, color or any other morphological or physiological trait, the individuals can be more or less successful because of them and therefore natural selection can filter the variations that are the fittest for that environment.
Without a control group there wouldn’t be any basis for knowing if a result is due to the variable being tested
