Answer:
Hypertonic blood draws water out of the interstitial fluid, which makes the interstitial fluid hypertonic. This, in turn, draws water out of the cells.
Basically an hype tonic blood has high solute potential,( low water potential) compare with the surrounding plasma and the interstitial fluid. Thus the interstitial fluid is hypotonic to the blood.
Consequently,water with higher potential moves from the interstitial fluid medium into the blood by osmosis through the capillary endothelial. This raises the water potential of the blood, lowering the solute potential, thus making it hypotonic to the interstitial fluid; which is now hypertonic(lower water potential ,due to loss to the blood by osmosis).
Since the interstitial fluids is now hyper tonic to the surrounding cells, water moves from the hypo tonic surrounding cells through osmosis into the interstitial fluids. The sequence continues until a stable internal environment is achieved,
We can confirm that if we used a minimal medium first and attempted to transfer from that to a complete medium second, certain types of bacteria would not be able to survive the first medium.
<h3>What bacteria would be affected?</h3>
This has to do with many kinds of bacteria, but particularly auxotrophs. These are bacteria who have trouble producing the substances they need to survive, so in an incomplete medium, these bacteria would not have a high chance to survive until moved to the complete medium.
Therefore, we can confirm that if we used a minimal medium first and attempted to transfer from that to a complete medium second, certain types of bacteria would not be able to survive the first medium.

Answer:
As the mass of the chest increases, more force is required to pull it.
Explanation:
Mass is a measure of the inertia of a body. Inertia means reluctance towards motion. A heavier object has a greater degree of inertia than a lighter object.
Hence, the student will notice that more force is required to move a heavier chest of books than a lighter one.
Therefore, as the mass of the chest increases, more force is required to pull it.
