Answer:
Spermiogenesis
Explanation:
Spermiogenesis is the stage during which the haploid spermatids are matured into sperms. It does not include any cell division.
The process of spermiogenesis includes elongation of spermatids and formation of acrosome at the top of its nucleus. A flagellum develops to make it a motile cell. There is an increase in the number of mitochondria while the excess of the cytoplasm is released outside.
All these events mature the haploid spermatid into a sperm cell having the capacity to reach and fertilize the egg.

Answer:
Natural selection is the application of pesticides.
Explanation:
Natural selection is a process which is non- random in which a trait increase or decrease in a population due to difference in the survival rate of a population that have that trait. So natural selection helps in the evolution of a population which is more adaptable.
Therefore when a pesticide is used against beetle many of the beetle die due to the pesticide but some beetles survived because they were having a gene that code for an enzyme that breaks down the toxin of pesticide which survived.
So nature selected those individuals who have genes that allow them to survive in changing and adverse conditions. So these selected individuals will reproduce and pass their genes to their offspring and increase in number.
Therefore by natural selection, more pesticide-resistant beetle will be produced and so more amount of pesticide should be needed to kill the beetles.
