vodomira [7]

This question lacks options, options are:

A.They maintain the cell’s shape.

B.They regulate cell processes.

C.They protect the body from infectious agents.

D.They signal the immune system to destroy pathogens.

E.They speed up biochemical reactions.

F.They send electrical signals.

The correct answers are C and D.

Explanation:

B cells and T cells use different biological weapons to attack the pathogen. The first secrete proteins called antibodies, which are distributed via the blood or the exposed surfaces to the environment, such as mucous. Antibodies are glycoproteins that circulate in the bloodstream looking for antigens that cause some type of damage to the body. Antibodies recognize and neutralize pathogens in a highly efficient way. Once the antibodies are produced, they remain circulating in the bloodstream for several months, which generates immunity for a long period of time to a certain antigen, in other words, they are capable of recognizing other molecules (antigens) in a very specific way and forming stable complexes with them (immune complexes). Its appearance in plasma is part of the adaptive immune response, in what is known as a specific humoral response, constituting a very effective defense against pathogens.

Compare hypertonic, hypotonic, and isotonic solutions. When an environment is hypotonic, what happens to the cell?
algol13

When an environment is hypotonic, the cell has more solute so solvent move from outside the cell to inside causing the cell to swell.

WHAT IS TONICITY?

  • Tonicity is the ability of a solution to induce water loss or water gain in a cell. A solution can either be; hypertonic, hypotonic or isotonic

  • A hypertonic solution has more concentration of solute than its surroundings while a hypotonic solution has less concentration of solute compared to it's surroundings.

  • If a hypotonic solution has less solute, this means that it will have more solvent (water). Based on the principle of osmosis, water moves from a region of high concentration to region of low concentration.

Hence, water will move into a cell that is located in a hypotonic environment, causing it to swell.
