wind and rain break down these minerals into small grains, like sand
The correct answer for this question is (D) It can proceed in the dark.
Calvin cycle is named after Melvin C. Calvin, who won a Nobel prize in chemistry for finding it in 1961. Calvin cycle take place in chloroplasts during photosynthesis and it is a <u>light-independent reaction so also called as dark reaction.</u>
The Calvin cycle proceeds in three stages:
1. Carboxylation, during which CO2 combines with ribulose-1,5- bisphosphate
2. Reduction, during which carbohydrate is formed at the expense of photochemically made ATP and NADPH
3. Regeneration during which the CO2 acceptor ribulose-1,5- bisphosphate is formed again so that the cycle continues.
D) Exercise is the answer

Proximal convoluted tubules (PCT)
Proximal
convoluted tubules (PCT) are first part of the renal tubule that extends from
the Bowman’s capsule to the descending arm of the thin loop of the Henle. PCT
is made up of cells that contain many mitochondria that produce ATP for the
energy –intensive resorptive processes.
Burial practices has not lead to significant changes in Earth’s biomes.
