Fragments of (LPS/NAM/NAG) released from Gram-negative bacteria into the bloodstream produce fever and shock.

The process illustrated in Figure 3.6 occurs in (eukaryotic/bacterial/archaeal) cells.

Describe how the structure of the bacterial cytoplasmic membrane relates to its function of selective permeability.

The presence of a cell (wall/membrane) enables bacterial and plant cells to resist the effects of hypotonic solutions.

Compare and contrast archaea and bacteria, with particular attention to the features that lead to their placement in separate taxa.
