Answer:
CD40L
Explanation:
The CD40 ligand (CD40L) protein is a transmembrane glycoprotein which is expressed on activated T cells and belongs to the tumor necrosis factor (TNF) superfamily. The hyper IgM syndrome is caused by mutations in the CD40L gene, where the defective protein can no longer bind CD40 on antigen-presenting cells. The X-linked Hyper IgM syndrome is characterized by abnormal levels of immunoglobulins, i.e., low levels of IgG and IgA, and increased/normal levels of IgM. Because CD40L gene is located on the X chromosome, this disorder is observed much more frequently in males than in females.

Explanation: all cell membranes need to maintain function
Answer:
The correct answer will be- arteries→capillaries→veins
Explanation:
The circulation of blood in the closed circulatory system flows through blood vessels. These blood vessels show structural differences in response to the pressure exerted by the blood on the surrounding medium.
The blood pressure varies in the circulatory system because the heart pumps the blood with a greater force, so the blood vessel called arteries which carries the blood from the heart posses thicker walls.
The blood pressure reduces until the blood reaches the organs, the blood pressure reduces. Thus the blood in the capillaries has lower pressure.
When blood exits from the organs back to the heart, then the blood pressure is highly reduced as a result, the veins carry the blood with lower pressure.
Thus, arteries→capillaries→veins are the correct answer.
Either A. or D. it depends on what kind of insulation you're looking for.
