What is the importance of NADH and FADH2? Multiple choice question.

A)These molecules are recycled for use in glycolysis.

B)These molecules are used in the electron transport chain.

C)These molecules are useless by-products.

D)These molecules are used as products in photosynthesis.

B) These molecules are used in the electron transport chain.

Explanation:

NADH and FADH2 are used by donating electrons to the electron transport chain. They both donate electrons by providing an hydrogen molecule to the oxygen molecule to create water during the electron transport chain

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.  

idk im sorry.
