During photosynthesis

a. light reactions produce sugar, while the calvin cycle produces o2.
b. light reactions produce nadph and atp, while the calvin cycle produces sugar.
c. light reactions photophosphorylate adp, while the calvin cycle produces atp.
d. the calvin cycle produces both sugar and o2.

B

Explanation:

The first stage of photosynthesis is the light reaction which occur in the thylakoid membrane of the chloroplast. Solar energy of light captured by chlorophylls, and is used to produce high-energy electrons of which in a series of reactions produces ATP and NADPH.

In the dark reaction of photosynthesis the ATP and NADPH are used to reduce CO2 to produce sugar

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
