Anatomy Lab Exercise 5

Question 1

solvent

Answer 1

a fluid that contains dissolved substances

Question 2

solute

Answer 2

substance dissolved in a solution

Question 3

active processes

Answer 3

processes that require cellular energy (ATP) to transport substances from an area of lower concentration to an area of higher concentration

Question 4

passive processes

Answer 4

processes that do not require the cell to expend energy because the kinetic energy of the particles causes them to move from an area of higher concentration to an area of lower concentration includes simple diffusion, facilitated diffusion and osmosis

Question 5

diffusion

Answer 5

random movement of particles from their greater concentration to their lesser concentration

Question 6

concentration gradient

Answer 6

indicates there is a difference in the concentration of molecules or ions inside the cell compared to outside the cell

Question 7

osmosis

Answer 7

water moving through selectively permeable membrane

Question 8

hypotonic solution

Answer 8

higher water concentration lower solute concentration

Question 9

hypertonic solution

Answer 9

lower water concentration higher solute concentration

Question 10

isotonic solution

Answer 10

equal water and solute concentration

Question 11

crenated

Answer 11

shriveled with spiked edges

Question 12

hemolysis

Answer 12

to burst a red blood cell

Question 13

receptor

Answer 13

the component of a feedback system that detects change in the external or internal environment

Question 14

positive feedback system

Answer 14

a feedback mechanism that reinforces the change in the controlled condition
