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,
yes B is the correct answer
As activators that increase transcription initiation or decrease action of transcription initiation of related gene, transcription factors that bind to enhancers have an impact on genes thousands of base pairs distant.
Because the DNA between the enhancer and the promoter loops out, transcription factors bound to the enhancer can communicate with the basic transcription machinery directly. A few proteins that act as transcription regulators bind to enhancers, that are regulatory components located outside the gene they are meant to activate. DNA sequences known as insulators prevent enhancers from working. Insulators may work by creating chromatin loops that connect interconnected areas of genes and regulatory components.

It is a true statement. We do this with tomatato plants all the time. If you have ever looked closely at a tomatato plant you will notice tiny hairs on it, each hair can grow a new root system. So I cut it off then place it in a grow seed tray with some support and it grows a whole new plant. You do have to remove the leaves except the very top ones say 15-20 leaves should be left on the plant you want a bare stem up to that. Also works witha variety of ivy plants.
