Answer:
The correct answer is option B. favorable change in DNA of the insect.
Explanation:
At the point when a pesticide is first utilized, a little extent of the pest population may survive to introduction to the material because of their particular hereditary or genetic makeup. These surviving individuals pass along the gene resistance to particular insecticide or pesticide to next generation.
Upon introduction to pesticides, insects that don't have the resistance die eventually, in this manner permitting the insects with the resistance genes to endure and reproduce,creates more resistance insects.

Explanation:
Primates are known to mature slowly compared to other mammals, they have a longer gestation period and longer period of infant dependency. Therefore the period between birth and adulthood is usually longer compared to other mammals, which then result to late age in their first reproduction.
For example humans have a gestation period of 365 days while baboons is 187 days compared to rabbits with a gestation period of about 33 days or mice with a gestation period of about 20 days
Of any primate, humans exhibit the longest period of infant dependency, Chimpanzee is about 5 years compared to other mammals.

Answer:
A Hypothesis leading to knowledge should be put through severe tests, which includes the estimation of previous knowledge.
According to <em>confirmatory data analysis</em> systems, <em>"Confirmatory research"</em> helps to estimate with precision the value of a hypothesis or findings in a specific study or report, by estimating and evaluating previous studies on the subject matter; since that report doesn't provide evidence for existing hypothesis or evaluates previous existing results on the matter, neither states the absence of it, your professor might point out that <em>"Your report does not attempt to test a hypothesis"</em>. Thereby the answer would be a.)
