Frage 1
Frage
Dissolved substance can move into and out of cells by diffusion
Antworten
- True
- False
Frage 2
Frage
Diffusion is the [blank_start]net[blank_end] movement of [blank_start]particles[blank_end] from [blank_start]high[blank_end] concentration to [blank_start]low[blank_end] concentration. The [blank_start]greater[blank_end] the difference in concentration, the faster the rate of diffusion
Antworten
-
high
-
low
-
greater
-
net
-
particles
Frage 3
Frage
how if diffusion used in our body
Antworten
-
in the lungs - oxygen passes through the cell membranes by diffusion in the mothers placenta in the gut, to the blood in capillary of villus in small intestine
-
the air into our skin
Frage 4
Frage
As the [blank_start]temperature[blank_end] increases, the amount of energy available for diffusion is increased. This means that a given particle will move [blank_start]faster[blank_end] (there is more energy >pushing= it) at a higher temperature. Thus the [blank_start]rate of diffusion[blank_end] will be faster as the temperature increases.
Antworten
-
temperature
-
faster
-
rate of diffusion
