Answer : option B) Gravity acting on the edges of plates and friction between the plate and the asthenosphere.
Explanation : The gravitational force acting on the edges of the tectonic plates raise a friction between the plate and the asthenosphere, which results into the motion of the tectonic plates.
Usually, the tectonic plates are found to move because of the intense heat produced from the Earth's core which causes the molten rock in the mantle layer to move and make a motion. It moves in a pattern which is called as convection cell that forms when the warm material rises, and cools, later eventually sink down producing the motion in the tectonic plates.
Answer:
The correct answer is 1.
Explanation:
The metabolism of homocysteine produces a sulfur amino acid that is normally formed from methionine during the fulfillment of its function as a donor of methyl groups. Metabolic fate such as remethylation and transsulfuration, involving the enzymatic forms of the vitamins folacin, B12, and B6, gives rise to homocysteine and mixed disulfides including so-called protein-linked homocysteine, the main form circulating in plasma. B6 deficiency would have a direct impact on the metabolism of homocysteine to cysteine.

Answer:
Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification.
Explanation:
I believe the conversion for mL to cm^3 is 1:1 so just change 7.5mL to 7.5cm^3 and then divide 64.5 by it to get 8.6g/cm^3
