True

False

Which term best describes a beaker solution of 41% sucrose that holds a dialysis bag filled with 25% sucrose?

		a. Hypertonic
		b. Isotonic
		c. Hypotonic

The motion of molecules is ordered and predictable.

True

False

Answer 1

1. The given statement is True
Brownian motion = Random movement of molecules

2. The given statement is True
Simple diffusion refers to the movement of molecules from high concentration to low concentration without the expense of energy and carrier requirements.

3. Answer: Option A is correct
Explanation:
Beaker solution = 41% sucrose
Dialysis bag = 25% sucrose
The beaker solution is hypertonic to the dialysis bag.

4. The given statement is False
Brownian motion = Random and unpredictable movement of molecules
