A star turns matter into energy by the process of nuclear fusion.

A star is a fusion reactor. Under enormous pressure, resulting from gravity, light nuclei of gases such as hydrogen merge to form helium, and since this process releases energy, the start begins to radiate the excess energy. Later on, helium fusion produces heavier elements, and so on.

DDT is an insecticide that was used extensively in the mid-1900s to kill mosquitoes. It was very effective at first, but after a

dlinn [17]

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.
