The immune system's red blood cells fight and destroy foreign antigens.
B.
White blood cells move through the body (to parts where they are needed) in the blood vessels of the circulatory system to destroy pathogens.
C.
The circulatory system's arteries cause the immune system to work harder by bringing oxygen-depleted blood to the infection site.
D.
Red blood cells released by immune cells cause increased blood flow to the infection site; this increased blood flow brings other red blood cells to the area more quickly.
The correct is actually D , this is a question I have reviewed before in the past and the correct answer is def D as I remember clearly , I forgot how I explained it but I know for sure the answer is D :)
Have a merry Christmas !
Capillary action pulls water into the root of a tree while the forces of cohesion and adhesion continually move the water up the tall tree.
Water is a polar molecule. Strong hydrogen bonds hold the water molecules together. This is a kind of dipole - dipole interaction and it accounts for the cohesive forces in water.
The forces of adhesion bind water to other surfaces. In the case of plants, the adhesive forces facilitates the interaction of water with the xylem cells.
Water enters into the roots of plants by capillary action. Capillary action alone is insufficient to move the water up the tree.
Hence, the forces of adhesion and cohesion, acting together can help water molecules to move up the top of a tall tree.

Answer:
Explanation:
Picture a root like a straw.
The chesion between individual water molecules causes water to move together while The adhesion forces between the water molecules and the inner walls of the tree is stronger than gravity so this cause the water at the root to rise, this is called capillary action.
