Norepinephrine is also known as noradrenaline. It is released in the central nervous system which has a wide set of function in the body. This help in the activation of the flight or fight response by boosting the body to have an increased attention and reaction time. THis can increase the heart rate, dilate blood vessels and increased blood pressure however in other tissue function may vary due to the presence of various receptors that this neurotransmitter can activate.

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.
