The quantity of water in the water table can change rapidly depending on the rate of extraction. As the level of water decreases in the aquifer, there is less available water to be pumped. If the rate of potential groundwater recharge is less than the rate of extraction, the water table will be too low for access.
The answer is natural killer cells.
Natural killer cells are a type of lymphocytes and they are important for the innate immune system. They recognise stressed cells much faster than other immune cells. Their response is rapid and usually only a few days after a viral infection. They also respond to <span>cancer cell </span>formation. While other immune cells can detect only those harmful cells that have specific markers on the surface of the cell membrane, natural killer cells can even detect those cells that miss markers for apoptosis.
Explanation:

They are further classified into: fish, amphibians, birds, reptiles and mammals.
I hope I've helped : )
Answer:
Option (2).
Explanation:
Ames test is used to identify the mutageneicity of the compound. The bacteria are treated with chemicals in the nutritive environment to determine whether the substance can acts as a mutagen or not.
The bacteria that can restore the biosyntheic activity in the environment can be considered as mutagen. The mutant bacteria can be easily identified in the Ames test.
Thus, the correct answer is option (2).
