A, because every sex cell is genetically different from on another
Reabsorption is the process
The mineral fluorite is the mineral form of calcium fluoride.It is also called fluorspar. Its chemical formula is CaF2.
The mineral fluorite is used in the process to make steel and aluminium. It is used <span>as a </span>flux<span> in the manufacture of steel and other metals to eliminate </span>impurities<span>.</span>
It is the process of movement of substances from a region of higher concentration to a region of lower concentration .

Answer:
C) The Calvin cycle requires ATP and NADPH, which require sunlight to be produced
Explanation:
The light-dependent phase of photosynthesis includes the photolysis of water molecules. The released electrons are passed to PSII to PSI via electron carriers and finally to NADP+ to reduce it into NADPH.
Transfer of electrons via electron carriers also generates the proton concentration gradient which in turn drives ATP synthesis. ATP and NADPH formed during light reactions are used in the Calvin cycle as an energy source and electron donor respectively.
Hence, to continue, the Calvin cycle requires the synthesis of ATP and NADPH in the presence of light.
