Answer:
C. extinction
Explanation:
For example, you have a dog that naturally salivates at the sight of food. The salivation is an unconditioned response that is generated by the an unconditioned stimulus which is the food you present to your dog.
If you decide to ring bell before presenting food to your dog, your dog would associate the sound of the bell with food. And each time you ring the bell, your dog would salivate even when food is not presented. This salivation is a conditioned response that is generated when a conditioned stimulus (sound of the bell) is presented.
If the conditioned stimulus (sound of the bell) is presented repeatedly to your dog without the unconditioned stimulus (food), extinction occurs. Meaning your dog would stop salivating when next it hears the sound of the bell over time. The association of the sound of the bell with food by your dog would be weakened and goes to extinct over time.

Answer:
Explanation:
My best bet is DNA methylation at the site of Tweedledum's leptin gene or Histone Acetylation at the site of Tweedledee's gene.
B/c DNA methylation is a process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription. So this is probably repressing Tweedledum's leptin gene trancription which is not happening in Tweedledee.
Additionally, Histone Acetylation at site of Tweedledee's gene increases her trancription b/c Histone acetylation causes DNA to be more accessible and leads to more transcription factors being able to reach the DNA. Thus, acetylation of histones is known to increase the expression of genes through transcription activation.

Answer: Option C.
An effect of experience dependent plasticity.
The optionC is mixed up with D. Option D should start from "that our 'nervous
Explanation:
The Greeble experiment was performed by Isabel Gauthier, a cognitive neuroscientist from Yale university. The Greebles is all about the invented novel objects used as stumli in the studies of psychology and recognition of face. The experiment illustrate an effect of experience dependent plasticity.
