Answer:The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
Explanation:
Adenosine Tri Phosphate
it is made of one adenosine and three phosphates.
At room temperature or about 25°C, potassium nitrate (KNO₃) has a solubility of about 38.7 grams per 100 mL of water. At this concentration, the KNO₃ solution is said to be saturated since it already contains the maximum amount of solute that the solvent can dissolve, thus, if you add more KNO₃ salt, it will no longer dissolve. When the solution has less solute than that of the saturation concentration, it is called an unsaturated solution, thus if you add more solute, the KNO₃ salt will still dissolve. If the concentration of the solution is greater than its solubility, the solution is said to be supersaturated, thus, if excess KNO₃ salt is added, crystals will start to form.
