A team of biologists develop a new drug, and one team member hypothesizes that the drug is incapable of freely passing across the plasma membrane and requires the help of membrane proteins to enter cells. Alternatively, another biologist on the team hypothesizes that the drug can diffuse passively across the plasma membrane like and can. Which of the following, if true about the drug, best supports the alternative hypothesis that the new drug will exhibit simple diffusion across plasma membranes?a. The drug is a small nongoiar moleaule. b. The drug is a small charged moleoue. c. The drug is a large polar molecule. d. The drug is a large charged molecule.

the drug is a small non polar molecules

Explanation:the membrane of human cells is a lipid bilayer membrane.this property of the cell regulates the type of substances they can enter into it.a cell is constantly in interaction with it's external environment and needs to take in materials for growth and metabolism.this movement in and out of the cell is determined by the

difference in the concentration of materials, in and outside of the cell.

Some molecules which are small and non polar can easily pass through the cell membrane.this is called simple diffusion.this is so because these small molecules can easily diffuse through the lipid bilayer of the cell membrane.

Molecules such as oxyhemoglobin gas, nitrogen gas ,carbon dioxide can easily pass through .

Thus the drug been discussed must be small and non polar

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.

explanation:

hope this !
