Which of the following is true of diffusion?
|
|
It cannot occur without a selectively permeable membrane
|
|
|
Molecules move against the concentration gradient
|
|
|
It is an active process
|
|
|
It happens faster when the concentration gradient is increased
|
Explanation:
Detailed explanation-1: -The rate of diffusion is directly proportional to the concentration gradient. Higher the concentration gradient, the faster the rate of diffusion.
Detailed explanation-2: -Answer and Explanation: The correct answer is b. Molecules will move from high to low concentration until equilibrium is reached. This is a passive process, so it does not require energy.
Detailed explanation-3: -The greater the concentration gradient, the quicker diffusion takes place.
