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.
Answer:
Basement membrane
Explanation:
Epithelial tissues is one of the four types of tissues. They are widespread throughout the body and form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands .
They perform a lot of functions such as absorption, excretion, filtration, diffusion, and sensory reception.
They are anchored to the underlying connective tissue by basement membrane. A thin, fibrous, extracellular matrix of tissue.
The basement membrane acts as a mechanical barrier that prevents malignant cells from invading the deeper tissues.
Glaucoma - a disease that damages the optic nerve that sends pictures to the pain. if left untreated, it can lead to loss of peripheral vision.
