Question

homeostasis - b.5c based on this information, are the paramecia likely in a hypotonic, isotonic, or hypertonic solution, relative to their internal concentration?

Explanation:

Step1: Recall solution - type definitions

Hypotonic: solution has lower solute concentration than cell. Isotonic: equal solute concentration. Hypertonic: solution has higher solute concentration than cell.

Step2: Observe paramecia

Paramecia have contractile vacuoles constantly working to expel water. This indicates water is entering the paramecia.

Step3: Determine solution type

Since water is entering the paramecia, the external solution has a lower solute - concentration than the internal concentration of the paramecia. So it is a hypotonic solution.

Answer:

hypotonic
