Women have two x chromosomes, compared to men who have one x and one y chromosome. Because of the two x chromosomes, one of them can override the other. In men they only have one x and one y, they don't have the extra x chromosome to override the allele.
12 is the total number of NADH FADH2 molecules that will be produced.
In each citric acid cycle, one molecule of FADH2 is formed during the conversion of succinic acid to fumaric.
The CAC is called a cycle because the starting molecule, oxaloacetate is regenerated at the end of the cycle.
It is also known as Krebs cycle. This is actually a part of a huge process called cellular respiration. The citric acid cycle captures the energy stored in the chemical bonds of acetyl CoA (processed glucose) in a step-by-step process, trapping it in the form of high-energy intermediate molecules.
NADH:- It is an energy shuttle that delivers high energy electrons to the electron transport chain where they eventually get to power the production of 2 to 3 ATP molecules.
FADH:- This is another energy shuttle that carries high energy electrons to the electron transport chain, where they will ultimately drive production of 1 to 2 ATP molecules.

Answer:
B. Organic Matter
Organic matter is what differentiate a mineral from a rock.
Easy:
The four chambers of the heart are the right and left atria, and the right and left ventricles. The main veins connected the heart are the superior and inferior vena cava, the main artery is the Aorta.
The first chamber, (the right atruim) recieves deoxygenated blood and forces it into the right ventricles which forces the blood into the lungs for oxygenation. Then the blood reenters the heart in the left atrium, which forces the blood into the left ventricle and then out the Aorta to the rest of the body.
sorry, but this question needed kind of a long answer to be answered correctly.
