Answer:
The situation in which some individuals have greater reproductive success than other individuals in a population. Along with variation and heritability, it is one of the three conditions necessary for evolution by natural selection.
There are so many factors that contributed to this over time, reproductive success differs and it could be attributed to hereditary and variation as well. Most often, the hereditary plays the most role out of all as the viability of both eggs and sperms could have been inherited from parents or being affected as a result of environmental factor or nutrition or other factors.
For instance, if one has a rhesus factor of negative and went ahead to marry another male counterpart with negative rhesus factor, this sedomly leads to miscarriage which could have been controlled had it been they were thoroughly counseled. Furthermore, physical factor such as accident could damage one spermatical vessicles that houses the sperm cells which render such an individual to be unable to donate a viable sperm cell for reproduction.
Those with high rate of reproductive success thrives as result of having many offspring which increases their chances of having more offspring than those with little success rate.

Enzymes are biological molecules that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. The vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.
There are thought to be between 60,000 and 200,000 protist species, and many have yet to be identified. Protists live in almost any environment that contains liquid water. Many protists, such as the algae, are photosynthetic and are vital primary producers in ecosystems.
We do science because if we didn't we would not know a lot of the things we do know now.
