When Cara is three, her parents learn that she has a rare brain disease that requires the removal of the right hemisphere of her brain. Given the research, which of the following results can her parents expect?a. Plasticity
b. Neurogenesis
c. Severe loss of function
d. Paralysis
e. better results if the surgery occurs when she is older: Younger brains recover more quickly and more fully than older brains.

The correct answer is - a, and b.

Explanation:

Plasticity is the ability of the change in the brain during course of life span. It is a remarkable ability to recovery after the surgery or removal of the part of the brain or injury to the brain.

The neurogenesis is the ability to the regeneration of the nervous system cell, it can occur in the adulthood as well however it takes approximately six week time.

Thus, the correct answer is - a, and b.

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
