A clinical research study is evaluating cells that bridge both the innate and adaptive immune systems. A nurse has identified the dendritic cells (DCs) as a key component. Which statement validates this finding

      The dentritic cells can sense all of the foreign patogens that can invade the body.

Explanation:

      Once a patogen comes into the body, the dendritic cells will recognize this patogen and send the information needed to create the right antibodies to protect your body of this invader. Once this happens, the body can start working in an adaptive way, because, if you don't have the right antibodies for the invader, the DCs will need to warn the body to produce lots of different kinds of antibodies, and with that, try to adapt itself to the virus or bacteria.

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.
