Answer: The answer is (D) prevent the passge of certian molecules into the cell.
Step-by-step explanation: We have four option out of which one describes the functions of protein present in the phospholipid bilayer in the cell membrane.
Phospholipid bilayers are critical components of cell membranes. Its function is to act as a barrier to the passage of molecules and ions into and out of the cell. It allows selective substances and molecules to come in and go out of the membrane.
Thus, the correct option is (D).

Answer:
A
0.1 is -1/10 which is obviously less than -1/7 .
Else we can also know by multiplying by 100
-1/10 *100 = -10
-1/7 *100 = -14.444
