Answer:
Animal cells tend to do best in an isotonic environment, plant cells tend to do best in
a hypotonic environment. This is demonstrated in the attached PDF.
Explanation:
A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst) when placed in a hypotonic solution, a process called cytolysis. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis.
I hope this helps. If not I am really sorry!

Answer:
d. an immediate increase in the concentration of antibodies, followed by a slow decline.
Explanation:
The Primary Immune Response is mediated by antibodies, which are gamma globulin proteins formed by plasma cells (B lymphocytes). Plasmocyte is a differentiated B lymphocyte capable of actively secreting antibodies.
Antibodies are produced with the main function of neutralizing and eliminating an antigen that stimulated their production. This elimination process is done in various ways through complement fixation, opsionization, anaphylactic reaction (mast cell degranulation), substance neutralization, agglutination, etc.
To neutralize the antigen, the primary immune response promotes an immediate increase in antibody concentration. This is usually a quick process. This concentration usually begins to decline in a slow process, but it will vary depending on the antigen.
Answer:
Heart disease is a non communicable disease because it does not happen due to any virus or bacteria.
Explanation:
Diseases caused due to virus and bacteria are mostly communicable. Heart Disease is caused due to poor supply of nutrients in hearts.
