Insect populations can develop resistance to insecticides over time. The evolution of resistance is associated with an increase in the frequency of adaptive genes in the population.
- In the case above described it is expected that a few mosquitoes in the population were resistant to DDT before it was ever used (Option a is correct).
- Dichlorodiphenyltrichloroethane (DDT) is a pesticide used in agriculture.
- After exposure to DDT, those individuals in the mosquito population that didn't carry gene variants (i.e., alleles) associated with the resistance to this pesticide died.
- Subsequently, insects having adaptive alleles associated with DDT resistance survived and reproduced, thereby increasing the frequency of adaptive genes/alleles in the population.

The weakest died out and only the intelligent and strong survived to pass on the most useful traits, determining the way a species evolved - growing more intelligent or athletic as a result of these patterns.
Answer:
Fruting bodies
Explanation:
Fungi can produce spores on somatic hyphae or on special spore producing hyphae which are arranged into structers called fruting bodies.

There would be unlimited number of sperms.
there would be 56 eggs. Hope it helps.
