Answer:
An organism has many benefits for having the ability to reproduce both sexually and asexually. The first of these benefits is that it doesn't have to find a mate in order to reproduce, so it can create offspring by itself, and enable the continuation of its' species.
Explanation:
Organisms that reproduce sexually mix their genetics with other individuals, meaning no two individuals are the exact same, genetically. This is beneficial because it decreases the likelihood an entire population will be wiped out by one threat, such as a disease, because many individuals will not be susceptible to the threat.
Organisms that reproduce asexually are able to do so at a much more rapid rate. In bacteria, they asexually reproduce by the thousands in hours because they do not have to rely on the complexities of sexual reproduction.

The vegetation in Cold desert biome is nearly absent due to the permafrost condition and other unsuitable conditions for the vegetation.
Only mosses and lichens grow in spring while even their vegetation is limited in all other seasons.
Apart from vegetation, the cold desert biome receives an annual rainfall of 6-10 inches, the animals do hibernate for longer times and they also burrow in order to escape the harsh climatic conditions. The soil in this biome is generally heavy and course due to weak chemical actions.
Hence, only statement ‘B’ is wrong and all other statements are right.
