Answer:
In hypertonic solutions, the cells will shrink and in hypotonic solutions the cells will fill up
Cells with cell walls will be able to control their tonicity better than cells without cell walls.
Explanation:
Cells with cell walls
- In a hypertonic solution (high solute concentration), water will flow out of the cell into the solution until equilibrium is reached. If the solution has a high concentration of solute the cell may undergo<u> plasmolysis where the plasma membrane detaches from the cell wall.</u>
- In a hypotonic solution: Water will flow into the cell because it has a higher solute concentration compared to the solution. This will continue until the cell is <u>turgid</u>. If more water continues to enter the cell, the cell is at risk of bursting, this takes a while because the cell wall will withstand the pressure.
Cells without cell walls
- In a hypertonic solution: Water will diffuse out of the cell, however there is no cell wall so cell is in danger of shrinking and dying.
- In hypotonic solution: Water will diffuse into cell,the cell will become turgid and if water keeps moving in the cell will burst because it has no cell wall to resist the pressure.
Answer:
The mouse population would be affected because of the relationship between mice and owls have in the food chain is competitive, thus meaning the mouse population would decrease.

Answer:
Big leaves cause water loss
Answer:
Diffusion- Passive transport
energy required- Active transport
exocytosis- Active transport
osmosis- Passive transport
endocytosis- Active transport
energy not required- Passive transport
facilitated diffusion- Passive transport
Protein pumps- Active transport
Explanation:
Passive transport can be described as the transport of particles along the concentration gradient i.e from an area of higher concentration to an area of lower concentration. This process does not require energy. For example, the phenomenon of osmosis
Active transport can be described as the transport of particles against the concentration gradient i.e from an area of lower concentration to an area of higher concentration. This process requires energy. For example, exocytosis
