The answer would be survival of the fittest.
This metaphor, "<em>survival of the fittest</em>," was used by Herbert Spencer to explain <em>natural selection. </em>It is sometimes also referred to as the survival for existence. This phrase came from the Dawinian theory of evolution where he explains that all species are capable of producing many offsprings. However, the survival of those offsprings depends on their ability to adapt to the risks and opportunities of the external environment.
<em>
</em>This relates to your scenario in the sense that fish lay a lot of eggs in the beginning but not all of them would live to achieve maturity. This is because even as eggs, they have many predators and are exposed to other elements. The threat pushes on even if they are able to hatch and grow up.

Answer:
The correct answer is c. cell fractionation
Explanation:
Cell fractionation is the technique which allows different cells part to be separated from each other on the basis of their density gradient by using a centrifuge.
In cell fractionation, first the cell wall and membrane of cells are broken by chemical, physical or mechanical method. Then the cell component can be separated by centrifuging them at different rpm.
Components that have higher density can be found in the bottom and the light density can be found on top of the tube. Therefore the correct answer is c. cell fractionation.
This must be a Choice question but the choices are not there so the only thing I can do is send you the four major ones and you can pick which one is not the major one for your question hope this helps don't worry about sending points I don't work care about him
What are the four major points of Darwin's theory of natural selection?
1. Overproduction - more offspring are born than survive
2. Genetic Variation - there is variation in the population
3. Struggle to Survive - organisms with suitable variations will survive and reproduce
4. Differential Reproduction - suitable variations are passed on to offspring
Well it depends on what type of mountain you are on and depending on which mountain you are on the temperature varies on the area.<span />
