Which statement describes the light reaction of photosynthesis?

Water molecules are split apart.

Air and water create energy for a plant.

Water molecules are combined to make food.

Carbon dioxide is put together with glucose.

Water molecules are split apart.

Explanation: In the light dependent reactions of photosynthesis, sunlight provides the energy for splitting of water into its components: hydrogen and oxygen. This reaction is known as the photolysis of water. The oxygen is evolved as a byproduct. In this light dependent reactions, the light energy absorbed is used for the splitting of water molecules and it is also conserved as ATP and NADPH which are used to drive the carbon fixation reactions of photosynthesis.

Many archeologists and anthropologists disagree with dr. thorne's view.  thorne strongly believes that what many calls "homo erectus"  was in fact  homo sapiens,  and that they migrated out of africa almost 2 million years ago and dispersed throughout europe and asia. that's way different  from what scientists have always believed about the evolution of the species.
