food
energy
oxygen
water
Which of the following is a sample of osmosis?
plant root absorbing mineral ions from the soil
the scent from a bunch of flowers spreads throughout a room
carbon dioxide move from air into leaves through stomata.
plant root absorbing water from the soil
Which of the following is a sample of active transport?
movement of oxygen from alveoli into red blood cell
movement of water across cell membrane
plant root absorbing mineral ions from the soil
uptake of water by the root hair of the plant
The cell below is in a _________ solution, because the solute concentration outside the cell is higher than the concentration inside the cell.
Hypotonic
Hypertonic
Isotonic
Plasmodic
Condition that occurs if too much water leaves a cell and the cell collapses.
Plasmolysis
Osmosis
Cytolysis
Exocytosis
What kind of solution would cause cytolysis (swelling until it bursts) of a red blood cell?
hypotonic
isotonic
ketonic
hypertonic
Your gums are swollen. How will rinsing with warm salt water help the swelling?
the salt will diffuse into your gums
salt lowers the pH
salt lowers the concentration gradient
water in your gums will diffuse out of the cells
What would happen to the height of water at A and B, if the purple molecules cannot pass through the membrane?
A would increase, B would decrease.
B would increase, A would decrease
Both A and B would increase
No change because there is no net flow of water.
When both inside and outside of a cell have the same concentration of water it is said that the cell has reached a state of...
Osmosis
Diffusion
Dynamic Equilibrium
Balance
The diagram shows two chambers with different numbers of molecules separated by a partially permeable membrane. Predict what will happen to the water molecules.
No net movement, as the chambers are at the same concentration.
Move from B to A due to osmosis
move from B to A due to active transport
move from A to B due to osmosis
If there is a 5% salt solution inside a cell and 5% salt solution outside a cell...
more water will move inside the cell
more water will move outside the cell
there will be no net movement of water
there will be no movement of water at all
The diagram shows an experiment using a potato. Which shows the result of the experiment after 24 hours?
A 2 cm cube of agar gel with phenolpthalein is placed into a beaker of acid. The acid diffuses through the gel at a rate of 2 mm/minute. How long does it take for the cube to turn clear?
1 minute
2 minutes
5 minutes
