Answer:
D. hotter rock rises and cooler rock sinks.
Explanation:
We know that as we move <u>towards Earth's center</u>, the <u>temperature rises</u>. This rise in temperature causes rocks to melt (magma). The high temperature and melting of rocks <u>decrease the density of material </u>which makes it <u>move upward</u>. By <u>moving upward</u>, the molten rock <u>starts turning solid</u> and becomes <u>denser again</u>. Here, it <u>sinks back due to gravity</u>. This upward and downward movement of rocks due to density and temperature makes a convection cell.
PS: The formation of convection cells in Earth's interior is also the reason for plate tectonics.
Answer:
Complete questions include: Answer Bank: Guanine nucleotides, uridine nucleotides, adenine nucleotides, cytosine nucleotides.
Explanation:
Glycine Auxotroph: Guanine nucleotides and adenine nucleotides (Purine nucleotides)
Glutamine auxotroph: Guanine nucleotides and adenine nucleotides (purine nucleotides)
Aspartate auxotroph: Guanine nucleotides, uridine nucleotides, adenine nucleotides, cytosine nucleotides Both purine and pyrimidine nucleotides)
The amino acids glutamine, glycine, and aspartate provide all the nitrogen atoms of purines in a two ring-closure steps to form the purine nucleus. Pyrimidines are synthesized from carbamoyl phosphate and aspartate.
