Groundwater
Is water that occupies pore space in the rock and soil layer beneath our feet, filling natural underground storage areas called aquifers, going on to feed into surface water sources like lakes, ponds, rivers, and even the ocean
Cellular immunity kills pathogens inside the cell, whereas humoral immunity destroys pathogens outside the cell.
<h3>What is the difference between Cellular and Humoral immunity?</h3>
The main difference between humoral and cell-mediated immunity is that humoral immunity produces antigen-specific antibodies, whereas cell-mediated immunity does not produce antigen-specific antibodies. The cellular immunity destroys pathogens and harm microbes that are present inside the cell, whereas humoral immunity kills pathogens outside the cell.
So we can conclude that cellular immunity kills pathogens inside the cell, whereas humoral immunity destroys pathogens outside the cell.

This blockage will likely increase the resistance to flow in his circulatory system, and as a result will decrease the rate of blood flow.
Blood vessels in the circulatory system transport blood away from and towards the heart. Arteries transport blood away from the heart, while veins transport blood back to the heart. The circulatory system transports oxygen, nutrients, and hormones to cells while also removing waste products such as carbon dioxide.
Vascular disease (vasculopathy) affects the blood vessels that transport oxygen and nutrients throughout your body and remove waste. Plaque (made of fat and cholesterol) slows or blocks blood flow inside your arteries or veins, causing common vascular problems. When there is too much cholesterol in the blood, the cholesterol and other substances can combine to form deposits (plaques) on the artery walls. Plaques can cause an artery to narrow or become blocked.

B makes the most sense because wind is constantly moving, and you can also use process of elimination. Wind has no pressure it’s only speed, so knock those out. Two air masses meeting would mean that they may have equal speeds against each other not really causing movement so it would be B. Hope this helps <3
