Answer:
hypertonic to water and hypotonic to salt solution.
Explanation:
<em>When two solutions of unequal solute concentrations are separated by a permeable membrane, water molecules move from the solution with lower solute concentration to the solution with higher solute concentration until an equilibrium is reached. The solution with higher solute concentration is referred to as being hypertonic while the other one is referred to as being hypotonic.</em>
The cells of celery stalks have higher solute concentration in their cell saps compared to the surrounding fresh water. Hence, water keeps entering the cells, resulting in turgidity. The cells are therefore hypertonic to fresh water.
The salt solution however seemed to have more solute concentration compared to that of the cell sap of the celery stalks. This made the cells of the celery stalks to lose water to the surrounding solution, resulting in flaccidity. Hence, the cells are hypotonic to salt solution.
Answer:
B
Explanation:
Wall cell has to be strong to bring protection to the cell. In general it is made of beta-glycosidic bonds.
Storage polysaccharides, are a source of available energy for the cell in any moment. Therefore, the bonds of storage polysaccharides need to be weak. In that way, when the cell needs energy from carbohydrates, it is not going to spend so much energy trying to break the bond.
Answer:
The answer is 55-60 degrees left anterior oblique (LAO).
Explanation:
During a cardiac series to observe the heart and the great vessels, the PA Projection of the chest, which is a term describing the x-ray's going through the patient's chest from a posterior to anterior direction, a 55-60 degrees left anterior oblique projection (LAO) should be used to get the best results.
