I hope this helped
Answer:
A semipermeable membrane is a barrier that will only allow some molecules to pass through while blocking the passage of other molecules. A semipermeable barrier essentially acts as a filter. Different types of semipermeable membranes can block out different sized molecules. A semipermeable membrane can be made out of biological or synthetic material.
Explanation:
Answer:
False
Explanation:
Active transport is one of the two major kinds of transport (the other being passive transport). Active transport involves moving substances against their concentration gradient i.e. from where they are low in concentration to where they are high in concentration. Hence, energy input in form of ATP is required by the cell to make this occur.
As stated in this question, the Na+/K+ (sodium-pottasium) ATPase pump is an example of active transport, which requires energy to move sodium ions. However, in active transport, substances are moved from a lower concentration to a higher concentration and not otherwise as depicted in this question, hence, it is FALSE.
