Fish lay a large number of eggs, few of which are fertilized and very few of which hatch into young ones. still fewer live to maturity and very few of these are fertile. which principles of evolution are represented in this example?

a. descent with modification and evolution
b. struggle for existence and survival of the fittest
c. adaptation and artificial selection

Option B, Struggle for existence and survival of the fittest

Explanation:

According to the Darwin’s theory of natural selection species which adapts themselves to the changing environmental condition in order to become efficient enough to survive and reproduce are termed as the “fittest” and thus he further stated that it is the “fittest” species which is able to survive.  

Option B also outlines the same concept and thus it is correct choice.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
