The lymphoid organ that acts like a filter as lymph passes through is

Lymph nodes

Explanation:

The interstitial fluid is used by cell for material exchange and present between the cells is collected by lymph vessels called as lymph. These vessels are designed so that the interstitial fluid can enter the vessel but the lymph can't exit from it. The lymph circulate throughout the body through these lymph vessels.

There are checkpoints in lymphatic system containing the white blood cells and present in various areas of body for the filtration of lymph are known as lymph nodes. It is kidney shaped organ and present in adaptive immune system. The major lymph nodes are located in above the colborne, in the armpits, tonsils, adenoid and on either side of neck linked to lymph vessels. These lymph nodes contain the macrophages which are phagocytic cells and when the lymph passes through the lymph nodes they act as military checkpoint and capture the diseased cells, cellular debris, bacteria and viruses. Infected cell such as cancer cells are captured by them and the particular lymph become swollen by the response such lymph nodes become swollen in upper respiratory infection.

the answer is b.) hydrogen bonds between bases.

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.
