The first stage of cellular respiration, glycolysis, results in two pyruvate molecules. those pyruvate molecules are then used in what stage of cellular respiration?

a. active transport
b. phosphorylation
c. the electron transport chain
d. the krebs cycle

The correct answer would be d. the Krebs cycle.

Explanation:

Cellular respiration is a bunch of metabolic processes and reactions that take place in the cells to convert chemical energy from glucose into adenosine triphosphate and then release waste products. Cellular respiration can be divided into three cycles - glycolysis, the Krebs cycle, and the ETS cycle.

In glycolysis glucose converted into two molecules of pyruvate. Oxidative carboxylation of the pyruvate molecule produces acetyl CoA. Acetyl CoA enters into the Krebs cycle which utilizes them and produces ATP.

Thus, the correct option is D. the Krebs cycle.

scientists have discovered that hiv does not cause aids by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. researchers from the gladstone institutes have revealed that hiv does not cause aids by the virus's

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
