The correct answer is "the formation of new brain cell connections as the result of reading a book".
Usually, neuroplasticity is apparent in young children when the central nervous system has an abundance of neurons. This is always in the context of forming new brain cell connections or synapses that will lead the person to access the information quicker. This also exemplifies the principle of use and disuse when it comes to knowledge.
The other choices concerns the skeletal system, cardiovascular system, and the endocrine/reproductive system; all of which do not have a relation with neuroplasticity.
Answer: Option C
Explanation:
Color blindness is a common hereditary condition which means it usually passes from parents. Red green color blindness is passed on from the mother to the son.
The chromosome number 23 is the sex chromosome also responsible for colorblindness. As it is sex linked the son can receive the recessive allele from the mother.
The mother of the child had a recessive allele which she transferred into her son. As it is sex inherited disease the son is affected by gene carried from mother.
