1. what is mitosis in a living cell? a. the separation of the genetic material of a cell into two completely identical sets, one for each of the daughter cells created during cell division b. the creation of two daughter cells with half the number of chromosomes that the parent cell has by the process of cell division c. the creation of a larger amount of cytoplasmic material that can then be split among the daughter cells of a parent cell d. the separation of existing genetic material by splitting chromatids at the centromere to create two similar nuclei in another cell 2. what is the best definition of diffusion? a. random movement of molecules across a concentration gradient until the difference in concentration between two regions is near zero b. a process in which molecules move across a semipermeable membrane until the number of molecules of water is nearly equal on both sides c. net movement of molecules across a permeable membrane bilayer that requires transport proteins d. the exchange of solute molecules across a permeable membrane from areas of high concentration to areas of low concentration 3. what characteristic makes osmosis different from diffusion? a. osmosis occurs through a semipermeable membrane. diffusion occurs through a permeable membrane. b. net movement in osmosis is from areas of higher concentration to areas of lower concentration. net movement in diffusion occurs from areas of higher concentration to areas of lower concentration. c. osmosis requires facilitation by an energy-carrying molecule, such as atp. diffusion requires no additional energy to move molecules across the concentration gradient. d. osmosis is used for gases, such as oxygen and carbon dioxide. diffusion is used for water that contains salt or sugar molecules.
