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.

telo118 [61]
The population of the mice would most likely increase. This is because the number of predators of mice will decrease. Predators are those that feed on others, in this case mice. When predators decrease, the prey (which would be the mice) will be able to populate thus leading to an increase in population.

Classify each statement as a description of glycolysis, glycogenesis, glycogenolysis, or gluconeogenesis.
loris [4]

Glycolysis is the breakdown of glucose where the final product is pyruvate, glycogenesis is the process of formation of glycogen and the product in first step is glucose-1-phosphate. Glycogenolysis is the process in which the initial reactant is glycogen, and gluconeogenesis is the formation of glucose from pyruvate.

<h3>What is glycogen?</h3>

Glycogen is a type of carbohydrate that is stored in the liver and gets converted into glucose in emergency situations.

It is formed by the process of glycogenesis and the first-step product is glucose-1-phosphate.

Glycolysis is the breakdown of glucose where the final product is pyruvate.

Glycogenolysis is the process in which have initial reactant glycogen and occurs when brain and muscle require immediate energy.

Gluconeogenesis is the formation of glucose from pyruvate.

Thus, these were the explanation for glycolysis, glycogenesis, glycogenolysis and gluconeogenesis.
