I believe the answer would be D because when they collide they move the Earth
C, a collection of photosynthetic protons arranged in a thylakoid membrane.
Answer:
As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity. However, at sufficiently high levels of light intensity, the rate oxygen evolution remains constant.
