The answer is B: Sister chromatid
<span>Investigations of the legacy of natural selection in the human genome have proved particularly informative, pinpointing functionally important regions that have participated in our genetic adaptation to the environment. Furthermore, genetic dissection of the intensity and type of selection acting on human genes can be used to predict involvement in different forms and severities of human diseases.</span>
Answer:
In Pavlov's study, the unconditioned stimulus (UCS) was __Meat_; the neutral stimulus was ___bell__; and, finally, the conditioned stimulus (CS) was __bell__.
Explanation:
Pavlov was a physiologist and was studying the digestive system but he came up with the most valuable studies of psychology. He put the tubes in dog mouth to collect saliva and calculate the amount of saliva produced by dog in response to different stimuli.
- He provided the meat to dog and dog produced saliva in response to unconditioned stimulus of meat. It was the natural reflex.
- He ring the bell but there was no saliva produced by dog in response to the bell. This was called as neutral stimulus.
- Then he associated the ringing of bell just before providing the meat (unconditioned stimulus). After several time the dog started to produce saliva on ringing of bell which was conditioned stimulus (CS).
