Three cases happen when a light wave strikes an object. Light waves can either be: absorbed, reflected or refracted. The differences are as follows:
a. Absorption - light stops at the object causing it to appear dark or opaque.
b. Reflection - this could happen either in a smooth or rough surface. On a smooth surface, for example mirror or glass, light bounces off the surface at angle equal to the incoming light wave. On a rough surface e.g. earth, light bounces at many angles because the surface is uneven.
c. Refraction - light goes through the object and bends at an angle. Typical thing you see when diamond or water is struck by light.
the answer is photosynthesis bcuz plants have to go thru the photosynthesis process to give off oxygen. hope the helps Brianliest??

Answer:
A. NADH and FADH2 both donate electrons at the same location.
Explanation:
In the respiratory chain, four large protein complexes inserted into the mitochondrial inner membrane transport NADH and FADH₂ electrons (formed in glycolysis and the Krebs cycle) to oxygen gas, reducing them to NAD⁺ and FAD, respectively.
These electrons have great affinity for oxygen gas and, when combined with it, reduce it to water molecules at the end of the reaction.
Oxygen gas effectively participates in cellular respiration at this stage, so its absence would imply interruption of the process.
NADH and FADH₂ electrons, when attracted to oxygen, travel a path through protein complexes, releasing energy in this process.
The energy released by the NADH and FADH₂ electrons in the respiratory chain in theory yields <u>34</u> <u>ATP</u>, however, under normal conditions an average of 26 ATP molecules is formed.
If we consider that these 26 molecules are added to the two ATP formed in glycolysis and two ATP formed in the Krebs cycle, it can be said that cellular respiration reaches a maximum yield of 30 ATP per glucose molecule, although theoretically this number was 38 ATP per glucose molecule.
They compete for food, water and space
