Explanation:
Answer:
C. placing cells in an environment with a lower solute concentration than that in the cells.
Explanation:
In pathological or diagnostic laboratories, to perform the differential leukocytes count (DLC) or white blood cells (WBC) count which are granulocytes, lymphocytes and monocytes we should first lyse the erythorcytes or red blood cells (RBC) with RBC lysis buffer. When RBC's lysis occur then only WBC's remain in the solution. Then, we add the hypotonic solution or lower solute concentration solution. By adding the hypotonic solution the cells will swell and increase in size.
So, the researchers used the hypotonic solution or lower solute concentration solution to increase the size of cells to differentiate between them.
Note:
In hypotonic solution the cells are increased in size or swell.
In hypertonic solution the cells are decrease in size or shrink.
In Isotonic solution the cells size remain same as normal.
Aldosterone is secreted in response to changes in
C. blood pressure
Answer:
Reproduction is important in plants to produce their progeny and to maintain its population. Plant reproduction helps to maintain its birth rate and sustain the ecosystem. Reproduction helps to acquire new variations and adapt to the environment with the most desirable characters.
