Diffusion is the movement of particles from an area of?
Low to high water potential
High to low concentration
Low to high concentration
High to low water potential
If temperature increases, what happens to the rate of diffusion?
Increases
Decreases
Stays the same
As we increase the temperature we are giving the particles more (a) energy so they diffuse more.
As we increase the surface area what are we doing to the rate of diffusion?
Increasing
Decreasing
Stays the same
As we decrease the surface area to volume ratio, what are we doing to the rate of diffusion?
Increasing
Decreasing
Stays the same
Large organisms such as humans have a (a) surface area to volume ratio
Small organisms such as protoctista have a (a) surface area to volume ratio
Which kingdom(s) contain only multicellular organisms
Animals
Plants
Fungi
Protoctista
Which kingdoms only contain unicellular organisms?
Plants
Fungi
Protoctista
Prokaryotes/bacteria
This kingdom can contain both unicellular and multicellular organisms
(a)
Increasing the distance (a) the rate of diffusion
If we increase the concentration gradient the rate of diffusion (a)
The lungs are adapted for diffusion by the walls of the alveoli being one cell thick to?
Increase concentration gradient
Increase diffusion distance
Decrease diffusion distance
Increase SA:V
The alveoli walls are folded to increase the rate of diffusion by?
Increasing SA
Increasing temperature
Decreasing SA
Decreasing SA:V
The lungs have millions of alveoli to increase the rate of diffusion by
Decreasing distance
Decreasing SA:V
Increasing concentration gradient
Increasing SA
The capillary walls being one cell thick and close to the alveoli increases the rate of diffusion by?
Increasing SA
Decreasing diffusion distance
Decreasing SA
Increasing diffusion distance
The capillaries and ventilation (breathing in and out) increases rate of diffusion by?
