i) The importance of DNA copying in reproduction:

DNA copying is a fundamental process in reproduction. It ensures that the offspring get the same blueprint or genetic code as their parents. This genetic code is what determines the traits and characteristics of the offspring. Without DNA copying, the offspring would not have the same genetic makeup as their parents, leading to significant differences in traits and characteristics.

ii) Variations are beneficial for the survival and stability of a species:

Variations are differences in the genetic information between members of the same species. They are beneficial for the survival and stability of a species for several reasons.

Firstly, variations increase the adaptability of a species to changes in the environment. If the environment changes, some variations may provide a survival advantage, allowing those individuals to survive and reproduce. This leads to the propagation of these beneficial traits in the population.

Secondly, variations increase the genetic diversity within a population. This makes the population more resilient to diseases, as there is a higher chance that some individuals will have a genetic resistance to any given disease.

Lastly, variations can lead to the evolution of new species. Over time, variations that provide a survival advantage can lead to the formation of a new species, ensuring the continued survival and stability of life on Earth.
