in <u>classical conditioning</u>, the stimulus or experience occurs before the behavior and then gets paired with the behavior.
Classical conditioning is a behavioral procedure in which a biologically potent stimulus (e.g., food) is paired with a previously neutral stimulus (e.g. a triangle). It also refers to the learning process that occurs as a result of this pairing, in which the neutral stimulus begins to elicit a response (e.g., salivation) that is typically similar to the one produced by the potent stimulus.
Classical conditioning is a fundamental behavioral mechanism, and its neural substrates are only now being discovered. Though distinguishing classical conditioning from other forms of associative learning (e.g., instrumental learning and human associative memory) can be difficult at times, a number of observations distinguish them, particularly the contingencies under which learning occurs.

Answer:
You will see an afterimage of the star in C. green hue.
Explanation:
The Opponent-Process Theory explains that an individual's perception of colors operates under 3 opposing systems:
- Black vs. white
- Red vs. green
- Blue vs. yellow
An individual perceives a hue based on 2 colors but he/she <em>can only see </em><em>one </em>of these opposing colors at once.
In this case, if you stare at a red star, you are looking at the red vs. green system so once you are done looking at the red, you will see the <em>green afterimage</em> of it, since green opposes red.
The correct answer is - fertile soil.
The Great European Plain, also referred to as the Russian Plain, is dominated by lowlands, naturally covered with dense grasses, and is known for its fertile soil. Most of the soil in this large plain is has very rich and deep upper, humus layer. The reason for this is that the grasses that grow their die out each year, and as they die out they decompose very quickly, giving the soil a new layer of decomposed biomass each year.
Because of the properties of the soil, this the region of Europe that is heavily used for farming, mostly crops like the wheat, hops, and corn. The conditions are excellent for them, they do not take a lot of the soil, and also contribute to keeping the soil very fertile constantly with their decomposing roots and steams.
