By controlling what enters and leaves a cell, the cell membrane A) aids in maintaining homeostasis within the cell. Homeostasis is the process by which organisms maintain life through eating, growing, and living in variable conditions. It would not make sense to answer B) because organisms do not control the homeostasis of their external environment. D) also would not be correct because cell's do not control osmosis in the external environment. The membrane does not control osmosis because osmosis is generally a random process of molecular diffusion whereas the membrane acts in a conscious and controlled way.

Answer:
True
Explanation:
Phnacetin can be produced using Williamson-ether synthesis. In this, phenacetin is derived from acetaminophen and the reaction involve interaction of alkoxide or phenoxide with a methyl or primary alkyl halide
In amide synthesis mechanism, acetic anhydride and phenetidine (p-ethoxyaniline) react to phenacetin through a nucleophilic acyl substitution
Hence, the given statement is true
