A.) An allele is a version of a gene that can be expressed as a phenotype.
The gestation period in cats stays for approximately 66 days and in every cycle a cat give birth more than 2 babies so if all cats are producing kittens at this rate, a prediction can be made that there will be lots of cats in our ecosystem. There will be cats everywhere if the number is not controlled.
As mentioned earlier, cats can starts reproducing at a young age of 6 months and right after delivery can get pregnant.
A mutation can allow a organism to adapt to the environment and example can be the case of the peppered moth which has two variations a white colored one and a black colored one. The white colored ones were able to survive better that the darker ones because of how they were able to camouflage with the lichen located in the trees. However, after a while smoke particles that were released by industries darkened the trunk of the trees making the white moths visible and allowing the darker colored ones to survive. Another example can be on how organism can be resistant to bacteria this allows the animal to survive and reproduce offspring with the same mutation. I hope this helps...

Biome is a combination of two words 'bio+ome,' which means life and its specified nature.
In simple terms, biome can be defined as a naturally occuring of a large number of flora and fauna that occupies major part of nature.

Biome not only consists of flora and fauna but also its abiotic factors such as the adaptation of animals in different environment.
Therefore, option B is correct.
Many metabolic prpcesses depend on water such as electron transport chain and glycolysis
