Answer:

Variation means certain change which occurs in sexually reproducing organisms because of errors in DNA copying.

Variations are beneficial for species because they give survival advantage even in the adverse environmental conditions.

Answer:

Variation is the differences between individuals within a species. This can be caused by inherited or environmental factors. Variation can be continuous or discontinuous. Biology. Inheritance and genetics.

2. In nature, variations occur during sexual reproduction. If this variation is beneficial to the species, it is selected and remains in the population. This is because the variant species are more adapted. Therefore, they can survive better and reproduce to pass the genes to the offsprings.

Variations are very important for organisms to survive because if there were no variations among living organisms there would have been no evolution or change and natural conditions do not remain constant they keep on changing. If variations stops then we would not be able to adapt to the changing conditions and can prove catastrophic to us.

3. Reproduction, unlike other life processes, is not essential to maintain the life of an individual organism. Reproduction involves creation of a DNA copy and additional cellular apparatus by the cell involved in the process. ... In fission, many bacteria and protozoa simply divide into two or more daughter cells.

Since a single cell divides to form two daughter cells, so the new cells produced need all the cellular apparatus to carry out the functions separately. Hence, DNA copying is accompanied by the creation of an additional cellular apparatus so as to distribute them equally among the new daughter cells.
