The correct answer is a.
When NASA sent the Apollo missions to the moon, they needed more accurate images of the moon's surface. NASA's Jet Propulsion Lab thus created a technology called digital image processing, which used computers to improve images of the moon. Later, researchers found that this digital image processing could also help to improve images of organs in humans, thus making a significant medical discovery.
<span>The correct answer is d) shake with fear. Classical conditioning is a learning process in which a stimulus that has biological significance (meaning it concerns survival) is associated with a stimulus that had been previously neutral of biological significance. For example, food is a biologically potent stimulus because we inherently want and need food. On the other hand, a bell is a neutral stimulus, because by itself it means nothing to us (we have no need for it). However, once we learn that the dinner bell ringing means food is being served, we associate the bell (a previously neutral stimulus) with food (a biologically potent stimulus). So, in the case of this question, Mikaya is associating the dock (a previously neutral stimulus) with the alligators that she saw (a biologically potent stimulus). Although this is a more negative example, in which the biologically potent stimulus is something that threatens survival, it still demonstrates classical conditioning. </span>
