➡️stream capacity to transport eroded material, and the nature of the material being transported✔️

➡️Gradient (Steepness or slope) ✔️

➡️Discharge (Amount of water carried at a given time) ✔️

➡️Load (The materials carried by a stream)
Rainfall (more rain more erosion). ✔️

What type of solution is this cell sitting in?
Dafna1 [17]

Answer:

The correct option is A. The cell is sitting in a hypertonic solution.

Explanation:

A hypertonic solution is a solution in which there are more number of solutes present in the solution than inside the cell. The solutes then tend to pass into the cell through diffusion from the solution.

As it can be seen in the diagram, the concentration of salt is more in the solution i.e 40%. Hence, the salt from the solution enters into the cell by diffusion and has a concentration of 10% inside the cell which shows the cell to be placed in a hypertonic environment.
