Answer:
C. extinction
Explanation:
For example, you have a dog that naturally salivates at the sight of food. The salivation is an unconditioned response that is generated by the an unconditioned stimulus which is the food you present to your dog.
If you decide to ring bell before presenting food to your dog, your dog would associate the sound of the bell with food. And each time you ring the bell, your dog would salivate even when food is not presented. This salivation is a conditioned response that is generated when a conditioned stimulus (sound of the bell) is presented.
If the conditioned stimulus (sound of the bell) is presented repeatedly to your dog without the unconditioned stimulus (food), extinction occurs. Meaning your dog would stop salivating when next it hears the sound of the bell over time. The association of the sound of the bell with food by your dog would be weakened and goes to extinct over time.
The reactants in photosynthesis are:

When glucose is taken into the cell, the fluids or solutions in the cell become more concentrated (due to the absorbed glucose) than the fluids outside the cell. When this happens, a natural process called osmosis takes place .
Osmosis is defined as the movement of molecules of a solvent (in this case water) through a semi-permeable membrane (in this case the cell membrane) from a less concentrated solution to a more concentrated one in a bid to to equalize the concentration on both sides of the membrane.
<span>Water will therefore leave the less concentrated solution outside the cell, pass through the cell membrane and into the more concentrated solution.</span>
