When do light independent reactions occur

Light-independent reactions are carried out in three steps, termed Calvin cycle collectively: carbon fixation, reduction reactions and 1,5-bisphosphate (RuBP) ribulosis. Even if the "dark" reactions are called, the Calvin cycle actually does not occur in the dark or at night.

Explanation:

Answer is above

Hope this helps.

Light-independent reactions take place in plant chloroplasts. In this process, sugars are made from carbon dioxide.

Explanation:

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
