Each of the major hypotheses proposed to explain why sexual reproduction is more widespread than asexual reproduction ultimately bases its explanation on the adaptive benefit of:. a. forming large populations.
b. forming genetically distinct offspring.
c. reducing mutation rates.
d. forming relatively slow-growing populations.
e. forming gametes of different sizes.

The correct answer is option b, that is, producing genetically distinct offspring.

Explanation:

It is found that sexual reproduction is more widespread in comparison to asexual reproduction primarily due to its adaptive benefit of producing offspring, which are genetically distinct. At the time of sexual reproduction, the genetic material of two individuals amalgamates to give rise to genetically-different offspring, which vary from their parents.

This tendency of reproducing sexually by the majority of eukaryotes is proof of its evolutionary success. The genetic diversity resulting due to sexual reproduction is considered to provide better chances of surviving in a modifying or unpredictable environment.

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

it would lead to upper respiratory infections and pneumonia.
