Mark knows that animals reflexively blink when air is puffed at their eyes. now mark wants to use this fact and classical conditioning to train a rat to blink when it hears a tone. he has just started presenting the tone to the rat. which step of classical conditioning is this?

Step 2 - presentation of the neutral stimulus.

Explanation:

Classical conditioning is the learning procedure in which the active stimulus when mixed with neutral stimulus elicit a strong response. This conditioning was explained by Pavlov.

In the given situation, the tone acts as the neutral stimulus. This stimulus will combine with the puffing that acts as the other strong stimulus and result in the blinking of the animals. Here, Mark shows the step 2 of the classical conditioning.

Thus, the answer is step 2 - presentation of the neutral stimulus.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
