The scientific discipline concerned with naming organisms is called

• taxonomy.
• cladistics.
• binomial nomenclature
• systematics
• phylocode

The correct sequence, from the most to the least comprehensive, of the taxonomic levels listed here is

• family, phylum, class, kingdom, order, species, and genus.
• kingdom, phylum, class, order, family, genus, and species.
• kingdom, phylum, order, class, family, genus, and species.
• phylum, kingdom, order, class, species, family, and genus.
• phylum, family, class, order, kingdom, genus, and species.

Which of these is the most common compound in the cell walls of gram-positive bacteria?

• cellulose
• lipopolysaccharide
• lignin
• peptidoglycan
• protein

Penicillin is an antibiotic that inhibits enzymes from catalyzing the synthesis of peptidoglycan, so which prokaryotes should be most vulnerable to inhibition by penicillin?

• mycoplasmas
• gram-positive bacteria
• archaea
• gram-negative bacteria

Which of the following requires ATP to function, and permits some species to respond to taxes (plural of taxis)?

• endospore
• sex pilus
• flagellum
