chemicals that can kill the prokaryotic
bacteria without harming eukaryotic cells.
37.
differs from osmosis in that pressure is applied to force water and dissolved
materials across a membrane.
38. In
either insulin is absent or the cells are insensitive to insulin, so glucose does
NOT get into cells, as it should.
