Answer:
From this it can be deduced that the fresh water is hypotonic and the salt solution is hypertonic to the cells of the celery stalks.
Explanation:
When submerged in water, the celery stalks become stiff and hard, this shows that water moves within the stalk, thus, water is hypotonic in comparison to the celery stalk. Therefore, water moves from the region of higher concentration to the region of lower concentration.
When the same celery stalk is administered into the 0.15 M solution it turns soft, which shows that water from the celery stalk moves out. Thus, the salt solution is hypertonic in comparison to the celery stalk. Therefore, freshwater is hypertonic and the solution of salt is hypertonic to the celery stalk cells.
The period is the time it takes the satellite to make a complete orbit around the central object. As the distance increases, so does the period because the orbit becomes longer because the radius increases.

Cell saps are the liquid inside of a plant cell's large central vacuole, which acts as support in order for it to function. They're made up of amino acids, glucose, salts and water and plays an important role in osmosis.
Cytoplasms, on the other hand, are a jelly-like substance between the cell membrane and nuclear envelope within a eukaryotic cell. They're mostly made up of water and salt, and aid in growth and metabolism in a cell.
The hydrophilic molecules are the polar molecules which establishes the hydrogen bonding with the water molecules. Hence the hydrophilic molecules are water loving molecules. The hydrophobic molecules are unable to establish any hydrogen bonding with the water molecules. Hence the hydrophobic molecules are water repellent molecules.
