<span>Even though surrounded by desert and sand, Egypt depends on
the Nile River. This river sometimes flooded, but also assisted the farmers in
farming. Egyptians did not have to worry about desert. The Nile often would
deposit quite a bit of rich dark soil called “kemet” in Egypt after a slight
flood, one that can’t do a lot of damage. In the outer regions of Egypt, the desert did hurt them by having droughts and damaging dry weather. Nevertheless, the Egyptians formed a way of irrigation, moving water from one place to another.

In Pavlov's original experiment, the bell began as a(n) neutral stimulus and by the end became a(n)s; conditioned stimulus.
Bell ringing was first used by Pavlov as a neutral stimulus. A stimulus that triggers an instinctive response is known as an unconditioned stimulus. Food served as the unconditioned stimulus in Pavlov's experiment. A reflexive response to stimuli is referred to as an unconditioned response. In his experiment, the dogs would slobber in response to food, but after numerous presentations of the food combined with the sound of a bell, the dogs would start to slobber in response to the sound alone. The bell's tone served as the conditioned stimulus in this instance.
A neutral stimulus is one that first causes only the attention to be focused, not any particular response. In classical conditioning, the neutral stimulus transforms into a conditioned stimulus when combined with an unconditioned stimulus.
