The blood flows through the blood vessel to it gets to a opening in the blood vessel .then the blood flows into the open space in the body and baths the organs
Answer:
A. complex I
B. complex II
Explanation:
Complex I of the electron transport chain is NADH dehydrogenase. It has FMN and Fe-S prosthetic groups. Complex II of ETC is the succinate dehydrogenase. It also has FAD and Fe-S as prosthetic groups. Both complexes I and II lack any type of heme as a prosthetic group. Complex III (cytochrome c oxidoreductase), cytochrome c and complex IV have heme cofactors. Heme A is present in a-type cytochromes while heme C is present in c-type cytochromes.
Observe it. I would observe the features of it, and research it
Chargaff's rule states that A (adenine) only bonds with T (thymine) and C (cytosine) only bonds with G (guanine) in a DNA strand. Since DNA replication is semi-conservative, this complementary base pairing allows two of the DNA molecules to be identical to each other as they have the same base sequence. The new strands made are complementary to their template strands and also identical to the other template. Complementary base pairing is important in the conservation of the base sequence of DNA because adenine always pairs with thymine, while guanine pairs up with cytosine. All in all, complementary base pairing has a huge role in the conservation of the base sequence of DNA.
