Answer:
Light-dependent reactions
Explanation:
First of all, the light-independent reactions and the same thing as the Calvin cycle, so your teacher wouldn't put them in the same question if one of them was correct. Aside from that, even if you have no idea what these things are we can use the names of them to see which one light is involved in. Aha! It's the light-dependent reactions because they're dependent on light (and water) to make the chemical energy (NADPH and ATP) to pass on to the next stage, the light-independent reactions.

Answer:
12 chromatids.
Explanation:
If a cell has 6 chromosomes in the G2 phase will have 12 sister chromatids during that same phase because replication of chromosomes occurs which produces two exact copies of each chromosomes. Then 6 chromatids are distributed in one daughter cell while the other 6 chromatids are distributed in other daughter cell and finally the cell division occurs.
