If the fertilizer is placed around the root of a tomato plant, the leaves of the plant will shrivel and turn brown. This phenomenon in terms of tonicity is that;
- inside the root cell is hypotonic since it contain more water than surrounding .
- In the other hand the cell is hypertonic since it contain more solute from fertilizer.
- Through osmosis water move out of the cell therefore the it turns to brown.
Answer:
Epithelium
Explanation:
Epithelium are tissue massage found mostly in the skin and serve as protective covering for the internal and external parts of the body.
A major characteristic of the epithelium is that its layers do not contain any blood vessels such as the artery or vein. The surface of the cells is also usually open to the internal cavity of the organ.
The most important mineralocorticoid regulator of electrolyte concentrations in extracellular fluids is Aldosterone.
Aldosterone hormone is produced by the adrenal gland, it acts in the functional unit of the kidneys to aid in the conservation of sodium, secretion of potassium, water retention and to stabilize blood pressure. The hormone causes water to be absorbed along with sodium ions which increases the blood volume and therefore blood pressure. It indirectly regulates blood levels of electrolytes and helps to maintain the blood pH.
The water will move out of the fish by osmosis due to existence of concentration gradient .
