3. A student was conducting an investigation using an unicellular organism called a paramecium. Paramecium maintain homeostasis by using a contractile vacuole to move water across their membranes. When paramecium are placed in distilled water a hypotonic solution, they are under distress
Which of the following most likely explains how the paramecium were able to maintain homeostasis in the distilled water environment that put them under distress?
The paramecium removes the extra water it absorbed.
The paramecium absorbed extra salt to change its concentration
The paramecium absorbed extra water to replace what it lost.
The paramecium shrank so it required less water.
