It should be natural selection since there is no external influence implied. (like environment or genetic mutations.)
There exists the same question with the following choices.

<span>2.Meiosis provides for chromosomal variation in the gametes produced by an organism. </span>
<span>3.Equal numbers of eggs and sperm are produced by meiosis. </span>
<span>4.The gametes produced by meiosis ensure the continuation of any particular species by asexual reproduction.
</span>
The correct answer is <span>2. Meiosis provides for chromosomal variation in the gametes produced by an organism. It happened during cross-over and segregation and law of independent assortment.</span>
Am certain that Creatine phosphate functions in the muscle by storing energy that will be transferred to ADP to resynthesize ATP. All muscle cells have a little ATP within them that they can use immediately, however, only enough to last for about 3 seconds. Therefore, all muscle cells contain a high-energy compound called creatine phosphate which is broken down to make more ATP quickly.
