A cell is in ISOTONIC SOLUTION when solute concentrations inside and outside the cell are equal.
<span>When cells are in isotonic solution, movement of water out of the cell is exactly balanced by movement of water into the cell</span>.
Other movement of water in the cells are hypotonic solution and hypertonic solution. Hypotonic solution is where concentration of dissolved solutes are less outside the cell than inside it. Hypertonic solution is where concentrations of dissolved solutes are greater outside the cell than inside it.

Answer:
Intracellular mediator or the secondary messenger molecules
Explanation:
The hormones act on the target cell or a group of target cells by binding to the hormone receptors present in the membrane of the target cells.
The hormones which are composed of the lipids bins to the intracellular receptors but the amino acid-based hormones are not able to diffuse into the cell and thus binds to the membrane-bound receptors.
This involves the signal transduction by the production of the secondary messenger molecules. The messenger molecules act as intracellular mediators like the cyclic AMP, cyclic GMP and the cyclic CMP.
Thus, the secondary messenger is the correct answer.
Answer:
True
Explanation:
Some functions are involuntarily performed, such as breathing, digestion, heart beating, eye reflexes, etc.
Cells are the basic unit of life. Atoms make up molecules. molecules make up cells. cells make up tissues. tissues make up organs. organs make up organ systems and organ systems make up the human body. therefore, without cells, there is no life.
