Q1. A hypothetical bacterium swims among human intestinal contents until it finds the suitable location on the intestinal lining. It adheres to an intestinal lining using a feature that also protects it from phagocytes, bacteriophages, and dehydration. Fecal matter from a human in whose intestine this bacterium lives could spread the bacterium, even after being mixed with water and boiled. The bacterium is not susceptible to penicillin family of antibiotics. It contains no plasmids and relatively little peptidoglycan.

What have to be true of the cell wall of this bacterium?

Q2. Mammalian blood contains an equivalent of 0.15 M. Seawater contains the equal of 0.45 M. What will occur if red blood cells are transferred to seawater?
