Answer:
Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.

Answer:
(Cystoplasm) and (Ribosomes) are common in most living cells
Explanation:
Answer:
Meiosis.
Explanation:
Meiosis may be defined as the process of cell division in which a single parent cell divides into four daughter cells. This type of division occurs in the sex cells.
The meiosis division is also known as reduction division because the daughter cells contain the half number of chromosomes as compared with parent cell. The meiosis is divided into meiosis-I and meiosis-II.
Thus, the correct answer is option (C).
Answer:
Contains large polytene chromosome that permit visual inspection of genomic events.
Were used to study the genetic effects of mutations.
Were used to establish the concept of chromosomal inheritance.
Explanation:
<em>Drosophila melanogaster </em>is a model organism that is used by scientists to study the genes and effect of a mutation on the genes. Drosophila is used as a model organism as it has a very short life cycle and the offspring can be produced in a short duration of time.
Because of these characteristics, Thomas Hunt Morgan wanted to study the factors of inheritance on the <em>Drosophila</em> and concluded in the form of the chromosomal theory of inheritance by the effect of mutation on genes that lead to linkage mapping.
Also, the salivary gland of fruit fly contains the polytene chromosome which allows us to look into the gene events.
Thus, the selected options are correct.
