Question
1. Which homeostatic process moves particles against a concentration gradient?
dynamic equilibrium
passive transport
osmosis
active transport
2. Which process is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy?
hypertonic transport
active transport
passive transport
dynamic equilibrium
3. What would most likely happen to a unicellular organism if it was exposed to a hypotonic solution for an extended period of time?
It would shrivel and shrink.
It would swell but never burst.
It would swell and then burst.
It would not be affected.
4. Which movement of particles would be most affected by a disorder that causes damage to carrier proteins?
osmosis
passive transport
active transport
diffusion
5. The data in the graph are the result of a paramecium being placed in a hypertonic salt solution.A graph entitled Paramecium Contractile Vacuole Contractions has salt concentration on the horizontal axis and contractions per minute on the vertical axis. A very low salt concentration has 30 contractions per minute, low: 22, medium: 15, high: 8, very-high: 2.What change would most improve the usefulness of the graph?Replace the concentration descriptions with actual values.Plot contractions per second instead of contractions per minute.Remove the plotted points and just keep the line.Remove the name of the organism from the title.
6. Which best describes the difference between osmosis and diffusion?
Osmosis is the movement of particles from a high to a low particle concentration, while diffusion is the movement of water from a high to a low water concentration.
Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration.
Diffusion is the movement of particles from a low to a high particle concentration, while osmosis is the movement of water from a low to a high water concentration.
Osmosis is the movement of particles from a low to a high particle concentration, while diffusion is the movement of water from a low to a high water concentration.
