Front 1

the mean distance that all the points fall from the mean

Back 1

standard deviation

Front 2

molecules spread from high to low concentration until they are equally distributed

Back 2

simple diffusion

Front 3

determine whether an organism tends to lose or gain water from its environment.

Back 3

The tendency of water to move down concentration gradients, and the magnitude of those gradients,

Front 4

Relative humidity =

Back 4

wvd/swvd*100

Front 5

Partial pressure due to water vapor

Back 5

WVP

Front 6

Pressure exerted by water vapor in air saturated by water.

Back 6

SWVP

Front 7

(likely to be at or near saturation) will be greater when there is a high VPD

Back 7

Evaporated water loss from organisms

Front 8

Water is more concentrated in ________ environments

Back 8

freshwater

Front 9

________ ________(and all cells) can be viewed as an aqueous solution bounded by a selectively permeable membrane floating in an another aqueous solution.

Back 9

aquatic microrganisms

Front 10

Water activity =

Back 10

Water vapor pressure solution/Water vapor pressure pure water

Front 11

When a semipermeable membrane is involved we call this special case of diffusion . Note that the solute cannot cross the membrane

Back 11

osmosis

Front 12

Body fluids and external fluid are at the same concentration.
Body fluids have a higher concentration of water and a lower concentration of solute than the external environment.
Body fluids have a lower concentration of water and a higher concentration of solute than the external environment.
