Chapter 01: Cellular Biology MULTIPLE CHOICE 1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA with histones. Which of the following would also be observed by the student? a. A single circular chromosome b. A nucleus c. Free-floating nuclear material d. No organelles ANS: B The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its nucleus; thus, the nucleus should be observed. A single circular chromosome ca...

Answer: Lipids, proteins, and polysaccharides Q: Why do we need a cell membrane? Answer: To keep the ICF and ECF separate, structure, protection, activation of cell, transport, and cell-to-cell interaction Q: How is osmolality different between ICF and ECF? Answer: The osmolality of ICF and EC...

What do you think would happen if the elastic fibers in tissues were distensible but not elastic? - ANSWER This would cause the tissues to be unable to resume their original shape and size once the stretching forces were removed. Predict what would happen if the tight junctions in blood vessels were not functional. - ANSWER Tight junctions make the spaces between the cells relatively impermeable to water and many solutes. Nonfunctional tight junctions in blood vessels would allow much of the ...
