Lab partners, Mary and Jose, have drawn the diagram above to represent what they observed in their lab experiment. They think the sugar molecules have moved across the plasma membrane but they disagree as to why this has happened. Which statement below best argues the correct reason for the molecule movement? (DOK.2, AKS 2A) Question 22 options: The sugar molecules moved across the membrane through diffusion due to the higher concentration of molecules inside the cell and lesser concentration of molecules outside of the cell. The movement of molecules by diffusion doesn’t require energy. The sugar molecules moved across the membrane through active transport due to the higher concentration of molecules on outside of the cell and lesser concentration of molecules inside the cell. The movement of molecules by active transport requires energy The sugar molecules moved across the membrane through osmosis due to the higher concentration of water molecules outside the cell and the lesser concentration of water molecules inside the cell. The movement of molecules by osmosis requires energy. The sugar molecules moved across the membrane through facilitated diffusion due to the higher concentration of molecules outside of the cell and the lesser concentration of molecules inside the cell. The movement of molecules by facilitated diffusion doesn’t require energy, but happens via carrier proteins

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?
