Answer:
Ocean Currents
Explanation:
Ocean currents are the continuous horizontal and vertical directional movement of sea water. The movement is as a result of some forces acting on the water. Forces like; gravity, wind and water density.
Fairview and Washington are both near the ocean and the air temperature in Fairview is colder than the air temperature in Washington due to the ocean currents and their movements. The ocean currents come from different directions and pass through the two cities. This makes the air temperature in both cities different.

Answer:
A. B cells
Explanation:
B cells are involved in the specific immune response that exhibits specificity, memory and self-non-self distinction. This immune response is also called as adaptive immunity. B cells are produced in the bone marrow. An encounter of B cells with antigen activates them for multiplication.
The activated B cells produce plasma cells which in turn produce specific antibodies that bind to the specific antigens and start the adaptive immune response.
