Answer:
THE DIAPHRAGM
Explanation:
The diaphragm is present beneath the stage and above the condenser in a microscope. It is that rotating disk that can be seen just underneath the stage. The function of the diaphragm is to control the amount of light once the specimen or slide is placed on the microscope.
The diaphragm consists of holes of different sizes. These holes majorly function in varying the amount and intensity of light on the slide or specimen.
<h3><u>Variations are beneficial in natural selection:</u></h3>
- Natural selection is the continuous process of nature to filter the population.
- So, due the variation of genetics it increases the probability of changing the characteristics of the individual that will either survive or diminish in the nature.
- Variation is the key to the evolution process. Variation provides the uniqueness to the individual that is not heridated from the parents.
- This unique character actually interacts with the environment and helps in the game of natural selection.
