detoxification Dboth A amp B E both B amp C 17 You are studying a specific type of tissue in culture out of the body You are investigating the connections between the cells in this tissue and have as a tool a small dye molecule You inject dye into cells in one part of the tissue and find that later the dye has moved into cells far from the original injection site There is also no dye in the solution outside the cells From these data you conclude that the cells A must have tight junctions that prevent the movement of water between the cells B must have gap junctions that allow the diffusion of material between cells C must have adherans junctions that allow the diffusion of materials between cells Dmust have tight junctions that allow the diffusion of materials between cells E must have gap junctions that allow material to move out of one cell then back into another cell 18 Cellular material can move into and out of the nucleus A through nuclear pores that penetrate the double membrane B by simple diffusion through the nuclear envelope C by facilitated diffusion through the proteins in the phospholipid bilayer that makes up the nuclear envelope Dby active transport

of the above E only B amp C above 20 Active transport and endocytosis are similar in that both A transport a large amount of material at the same time compared to other processes B require energy to move material across the membrane C require a concentration gradient to move materials across the membrane D use transmembrane proteins to move materials across the membrane B only transport hydrophobic substances 21 Transport of an ion by facilitated diffusion requires A an ion channel and energy B a carrier protein and energy C an ion channel and a concentration gradient D only a concentration gradient E a small shortlived hole in the membrane 22 Inspired by watching the Olympics you decide you need to learn how to cross country ski After a long afternoon a companion notices that you are behaving erratically and suggests you are dehydrated After a trip to the ER they prescribe rehydration via IV fluids The nurse assures you that the distilled water solution you are being

relative to blood plasma and will cause your blood cells to swell C hypertonic relative to blood plasma and will cause your blood cells to shrink Dhypertonic relative to blood plasma and will cause your blood cells to swell E isotonic relative to blood plasma and you need a hypertonic solution 23 Nucleotides are composed of A a ribose sugar deoxyribose or ribose B a phosphate group PO4 C
