Depending on the nature of variations different individuals would have different kinds of advantage e.g., Bacteria variants which can tolerate heat have a better survival chances in heat wave in comparison to non-variant bacteria having no capacity to tolerate heat wave.

Contraceptive methods should be adopted as: . They help in spacing two children. . Thus helps in maintaining a woman's and child's health. . Better care and healthier society. . Also prevention of sexually transmitted diseases on using condoms. . More productivity and hence better economic status.

Reproduction results in production of more organisms of a type. This helps in perpetuation of species. Since there is copying of DNA involved, which may result in variation. Thus, reproduction provides stability as variation helps in better adaptability of a species.

Since we are mammals, the development of growing foetus takes place inside the mother's womb. Thus, during each cycle, the uterus prepares itself for implantation by increasing blood flow and thickening of uterine walls.

Thus, during each cycle, the uterus prepares itself for implantation by increasing blood flow and thickening of uterine walls. In case, fertilisation does not take place, the thickened wall is not required, it thus is shed along with blood and mucus in the form of menstrual flow.
How does the creation of variations in a species promote survival?

How does reproduction help in providing stability to populations of species?
Reproduction results in production of more organisms of a type. This helps in perpetuation of species. Since there is copying of DNA involved, which may result in variation. Thus, reproduction provides stability as variation helps in better adaptability of a species.
