Answer:
Explanation:
NADH and FADH2 are both electron carriers of the electron transport chain. NADH gives up its electrons starting from Complex I, which has a higher energy level compared to other complexes. Energy is given off to pump protons across the membrane by the time electrons are transferred to ComplexIII. More electrons are pumped across the membrane as electrons move to Complex IV. Because NADH commenced giving up its electrons from Complex I (higher energy level complex), more protons are pumped across the membrane gradient, which enables ATP synthase with more power to produce 3ATP molecules per NADH molecule.
On the other hand, 2 molecules of ATP are generated by FADH2 because it starts by giving up its electrons to ComplexII. It missed a chance to pump protons across the membrane when it passed Complex I. By the time the electrons reach Complex IV, less protons have been pumped. The lesser the protons to power ATP synthase, the lesser the ATP molecules produced.
The fact that they can breed but cannot produce fertile offspring shows that they are different species. T<span>hey may have different characteristics which means they cannot breed </span>successfully, too.
I hope this helps! :-)

Answer: A procedure in which stain is applied until the desired intensity of tissue coloration is attained
Explanation:
Answer:
This question lacks options, they are:
a)Cold forest
b)Tropical forest
c)Temperate forest
d)Cloud forest
e)Alpine forest
The answer is B. Tropical forest
Explanation:
Tropical forest is one of the forests found in nature. The tropical forest receives the best environmental conditions in terms of vegetation growth. Hence, it is said to contain the most diverse organisms in nature. This means that tropical forests holds more species of terrestrial organisms than any other forest or biome.
Therefore, tropical forests are believed to contain 50% of the Earth's terrestrial plants and animal species due to their biodiversity richness.
