Cell Homeostasis

Question 1

The data in the graph are the result of a paramecium being placed in a hypertonic salt solution.What change would most improve the usefulness of the graph?

Revolt · Accepted Answer

Replace the concentration descriptions with actual values.

Question 2

Which movement of particles would be most affected by a disorder that causes damage to carrier proteins?

Revolt · Accepted Answer

active transport

Question 3

Which best describes the difference between osmosis and diffusion?

Revolt · Accepted Answer

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.

Question 4

Which homeostatic process moves particles against a concentration gradient?

Revolt · Accepted Answer

active transport

Question 5

Which motion of particles across a membrane requires energy?

Revolt · Accepted Answer

from low concentration to high concentration

Question 6

Which best describes dynamic equilibrium?

Revolt · Accepted Answer

Particles are moving into and out of the cell, but their concentrations remain stable.

Question 7

Which solution would most likely cause a plant placed in it to become firmer and more rigid?

Revolt · Accepted Answer

hypotonic

Question 8

For diffusion to occur, which condition must be met?

Revolt · Accepted Answer

A concentration gradient must exist.

Question 9

In which kind of solution is the concentration of solutes the same inside and outside of the cell?

Revolt · Accepted Answer

isotonic

Question 10

Water makes up a large percentage of the body’s cells. For a cell to remain in homeostasis, there must be a mechanism to control water changes in the cells. The movement of water from an area of high water concentration to an area of low water concentration is

Revolt · Accepted Answer

osmosis
