Which option identifies the process distinguished in the following scenario? A prototype furnace uses only light, water, and carbon dioxide as inputs, and produces clean, renewable fuel.

nuclear fusion
nuclear fission
photosynthesis
artificial photosynthesis

D. Artificial Photosynthesis

Explanation:

A and B don't really make sense so you can remove those right away. So you are left with C and D

Lets look at C. Photosynthesis is when a plant takes light, water and carbon dioxide. That fits part of it but a furnace is not a plant.

Now D is artificial photosynthesis. We know artificial is a human made item and not natural occurring which fits the description of the furnace. So human made photosynthesis is another way you could put it. So the furnace, human made, goes through photosynthesis like a plant.

So D. is correct

i can ! i just need to know what the paragraph is! : p

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
