- 1. Multiple ChoiceCells need to bring in molecules to carry out cellular processes. Often, this requires moving the molecules across the cell membrane against the concentration gradient. How do these molecules get into the cell?passive transport by diffusionactive transport using ATPpassive transport by osmosisosmosis
- 2. Multiple ChoiceA person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which of the following has occurred?The swollen gums have absorbed the saltwater solution.The saltwater solution lowers the temperature of the water in the gums.The salt in the solution has moved against the concentration gradient.The water in the gums has moved out due to the high concentration of salt in the solution.
- 3. Multiple ChoiceThe cell membrane of the red blood cell will allow water, oxygen, and carbon dioxide to pass through. Because other substances are blocked from entering, this membrane is calledperforatedsemi-permeablenon-conducivepermeable
- 4. Multiple Choice
Look at the diagram of a cross-section of a cell membrane below. The cell membrane controls movement of materials into and out of the cell. The following particles are moving from high concentration to low concentration and are using a carrier protein. How would you describe this type of movement across the membrane?simple osmosisactive transportsimple diffusionfacilitated diffusion - 5. Multiple ChoiceLook at the cross section of a cell membrane of a eukaryotic cell. H+ ions are being pumped from a low concentration to a high concentration. How do you describe this type of transport across the cell membrane?active transportpassive transportfacilitated diffusionco-transport

- 17. Multiple ChoiceA salt water fish is placed in fresh water. What is the best question a researcher might ask to determine what adaptation the fish might need to help maintain homeostasis in the new environment?Can the fish remove extra water which enters its cells through osmosis?Can the fish replenish water which leaves its cells through osmosis?Can the fish breathe in water with a different dissolved oxygen content?Can the fish metabolize food in water with a different pH?
- 18. Multiple ChoiceA student was conducting an investigation with paramecium in distilled water. The paramecium was able to maintain homeostasis even though this environment put them under stress. Which of the possible hypotheses below most likely explains how the paramecium were able to maintain homeostasis?The paramecium removes the extra water it absorbedThe paramecium absorbed extra water to replace what it lost.The paramecium absorbed extra salt to change its concentrationThe paramecium shrank so it required less water.
