Answer: B
Explanation:
The T helper cell needs to acttivate the T cyctotoxic cell in order for the Tc cell to go do its work.
Once the TC cell is active it interacts with MHC-1 proteins on the surface of the infected host cell, this allows the Tc cell to recignise the host cell and begin secreting cytotoxins (perforins and granzymes) in order to degrade the infected cell and cause apoptosis (controlled cell death)
Answer:
A. Intracellular Thirst
Explanation:
There are two types of thirst and intracellular thirst and extracellular thirst. Extracellular thirst (dehydration) can be ruled out as it only requires water and salt to regenerate blood, at it's correct osmality. On the other hand, intracellular thirst (dehydration) can be corrected by drinking water alone. Therefore, the answer to this problem is intracellular thirst due to thirst for plain water.
