Answer:
(D) acetyl CoA, NADH, H+, and CO2.
Explanation:
The given explanation is about oxidative decarboxylation of pyruvate into acetyl CoA and carbon dioxide. The reactions are catalyzed by enzyme complex pyruvate dehydrogenase. During the reaction, pyruvate loses one of its carbon atoms in the form of CO2 and the rest of two carbons form the acetate which in turn combines with CoA to form the acetyl CoA.
Since it is an oxidative decarboxylation, the released electrons are accepted by NAD+ which in turn is converted into NADH + H+.
Overall, there is the formation of one molecule of acetyl-CoA, CO2 and NADH + H+ each from one molecule of pyruvate.
Anything in the environment that can cause a mutation is called as a mutagen.
Environmental mutagens include:
radiations, chemical, infectious agents, extreme heat.
The environment we live in has a real impact on whether we experience genetic mutations. The quality of water we drink and the air we breathe can actually effect the integrity of our DNA. Our bodies are designed to correct any mistakes, but dangers from the environment can increase our chances of ending up with a mutation.
Seeing that our species is constantly evolving, maybe it is starting to get more uncomfortable to walk on all fours.

Rocky surfaces is the characteristic that both Mercury and Mars share. Mercury has a solid surface that is covered with craters and the surface of Mars is rocky and covered with canyons, volcanoes and craters all over it.
Other characteristics differ a lot. Mercury has no moon but Mars has 2 moons. Both Mercury and Mars have a thin atmosphere. Mercury has no to thin atmosphere. And temperature fluctuations are very vast between the two planets.
