Answer:
Prokaryote! The ones with a nuclear membrane are Eukaryotes.
They should probably be open-minded, as they have to find new scientific discoveries and such.
The cell membrane is made of two layer of phospholipid called phospholipid bilayer. Phospholipid has a hydrophilic head and hydrophobic tail. The hydrophilic head stick out on the membrane, pushing polar substance that go inside. Hydrophobic substance would be easily pass through the membrane while the hydrophilic doesn't.
If the active form of this drug is polar, then the substance would be hydrophilic. The drug should pass the membrane through active transport like carrier mediated transport or endocytosis.
