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

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

a compound light microscope is used to magnify objects in steps.
