Answer:
Explanation:
A turtle naturally withdraws in its head and limbs when its shell is tapped. You want to teach your turtle, by classical conditioning, to withdraw its head and limbs when you say "Boo." Consequently, you say "Boo" and then tap its shell on numerous occasions. Eventually your turtle withdraws its head and limbs when you say "Boo" alone. In this example, the Conditioned Response (CR) is to withdraw its head and limbs when you say "Boo."
A conditioned response is a behavior that does not come naturally, but must be learned by the individual by pairing a neutral stimulus with a stimulus.
In this case the neutral stimulus will be saying the word Boo the other stimulus is tapping its shell to produce withdrawing its head and limbs
Scientists should definitely use evidence - and they collect this evidence though especially designed experiments. Based on their data and assumptions they build models which they then test, but they can base their conclusions based on the models too.
What they should not do is based the conclusions on opinions, because opinions are not imparcial- they can state them as opinions, but not as conclusions.
