The role of oxygen in photosynthesis and in cellular respiration is: <em>Oxygen </em><em>is a product of </em><em>photosynthesis </em><em>and a reactant in </em><em>cellular respiration</em>.
<h3>What is Photosynthesis?</h3>
Photosynthesis is the process whereby green plants manufacture their food using energy from the sunlight, carbon dioxide and water to synthesize food in form of glucose and produce oxygen as a by-product.
<h3>What is Cellular Respiration?</h3>
Cellular respiration is a metabolic process in living organisms whereby glucose is broken down with the aid of oxygen, to release chemical energy.
Thus, the role of oxygen in photosynthesis and in cellular respiration is: <em>Oxygen </em><em>is a product of </em><em>photosynthesis </em><em>and a reactant in </em><em>cellular respiration</em>.

Answer:
There are two ways to solve this question. The faster way is to multiply each side of the given equation by ax−2 (so you can get rid of the fraction). When you multiply each side by ax−2, you should have:
24x2+25x−47=(−8x−3)(ax−2)−53
You should then multiply (−8x−3) and (ax−2) using FOIL.
24x2+25x−47=−8ax2−3ax+16x+6−53
Then, reduce on the right side of the equation
24x2+25x−47=−8ax2−3ax+16x−47
Since the coefficients of the x2-term have to be equal on both sides of the equation, −8a=24, or a=−3.
The other option which is longer and more tedious is to attempt to plug in all of the answer choices for a and see which answer choice makes both sides of the equation equal. Again, this is the longer option, and I do not recommend it for the actual SAT as it will waste too much time.
The final answer is B.
