A dialysis tube with a semipermeable membrane is placed in a beaker of water for about 45 minutes. The dialysis solution inside the tube contains distilled water, sodium chloride (NaCl), glucose, starch, and albumin. Sodium chloride is the smallest molecule and the rest are large molecules. How does the concentration of NaCl in the dialysis tube and the concentration of water in the surrounding beaker change through diffusion/osmosis?

Explain light independent reactions

Keeping in mind the life cycle of bacteriophages, consider the following problem: during the reproductive cycle of a temperate bacteriophage, the viral dna inserts into the bacterial chromosome where the resultant prophage behaves much like a trojan horse. it can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. as stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?
