The correct answer is A. The oxygen molecule accepts electrons from a compound called cytochrome a3. Cytochromes contain a central Iron atom that can either be in the oxidised state(ferric state) Fe3+ or reduced state(ferris state) Fe2+. The cytochrome is oxidized by giving the electron to O2(O2 is reduced).O2 becomes 2O- that quickly react with H+ to form H2O.
Accoring to the Chargaff's first rule of base pairing, each of the four nucleotide bases has its own complimentary match, that it always bids with.
So, Adenine always bonds with Thymine and Cytosine always binds with Guanine.
If you know the concentration of one base, in our case Cytosine, then you can easily calculate the percentage of other bases.
Since Cytosine and Thymine are always paired, there is an equal amount of both of them -16%.
So, 16% C + 16G = 32% of the whole DNA.
This means that the other two base pairs A and T make up to 68% of the DNA.
Half of the 68% is Adenine = 34% and half of it is Thymine- 34%.
So, the percentages of base pairs in the DNA sequence are :
16% C
16% G
34 % A
34 % T
Answer:
The correct answer would be B, parts of Iceland are moving apart
Explanation:
A divergent plate boundary means areas where the plate is moving away from each other. It is pushing away from the other plate which ultimately causes a rift valley. I hope this helps you! :)
