Answer:
Compressibility is reducing the volume by increasing the pressure of a substance like liquid or gas. It is a physical characteristic of a substance especially gases.
Everyday life examples:
(1) LPG - These gas cylinders have compressed natural gas to liquid gas to store and use as fuels.
(2) Tubes of bicycles are filled by the pumps that compress the air.
(3) Carbonated soda filled with the help of compressing the carbon dioxide into the bottle.
4) oxygen bottles in medical institutes for helping the patient to breathe.
I'm pretty sure its a because we already know that the dependent variable is "100 are given psychological test to assess their level of depression" and the experimental group is the one that took the 8 weeks of therapy and the control group is the group that we're on the waiting list for 8 weeks therefore the answer is A.independent variable
Hoped this helped ❤️
Answer:
Humoral immunity:
Humoral immunity is mediated by the macromolecules present in the extracellular fluid. This immunity provides protection against the pathogens present in the extracellular fluid. B- cells are mainly produced by the humoral immunity. The plasma cell and memory cells are generated in the human body. Antibodies kill the pathogens in humoral immunity.
Cell mediated immunity:
Cell mediated immunity is activated by the infected cells. This immunity provides protection against intracellular pathogens. T- cells are mainly produced by cell mediated immunity. T helper cells and T killer cells are mainly produced in the cell mediated immunity. Cytokines kill the pathogens in case of cell mediated immunity.
