The diagram below illustrates a cellular process. Cell membrane
Cytoplasm
Which of the following best explains the process illustrated in the above diagram?
A Passage of water molecules through a semi-permeable membrane to equalize concentration
B.
Transport of molecules across a membrane from a high to low concentration gradient by means of a carrier protein
Movement of molecules against a concentration gradient expending energy
D.
Separation of suspended particles from a fluid environment to a non-fluid environment through a porous membrane

B. Transport of molecules across a membrane from a high to low concentration gradient by means of a carrier protein

Explanation:

According to this diagram showing the presence of certain molecules on one side of the membrane, making their way to the other side across the membrane. Due to the difference in concentration on either side of the membrane, a concentration gradient is formed.

Based on the diagram, the movement or transport of molecules is occurring from a region of high concentration to a region of low concentration. This means that it's a form of PASSIVE TRANSPORT, however, the molecules are being transported across via the aid of CARRIER PROTEINS as depicted in the image.

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition
