In what way are the light-dependent and light-independent reactions of photosynthesis similar?
both require chemical energy to proceed.
both occur in the chloroplast.
both produce oxygen as a byproduct.
both involve carbon fixation.

The correct answer is Both occurs in chloroplast.

Chloroplasts are organelle present in plant cell that  serves as the main site for photosynthesis. Both the light-dependent reaction and the light- independent reaction take place occurs in chloroplast. The light-independent reaction or the dark reactions occurs in the stroma, that is the fluid filled area of the chloroplast. The light dependent reaction takes place in the thylakoid membrane

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
