b) In the lag phase, cell death exceeds cell division.
c) Bacteria typically divide by budding, producing a daughter cell that is smaller
than the parental cell.

waste accumulation.
Bacteria of the genus Mycoplasma are distinguished from other bacterial cells by
1) cell walls composed solely of amino acids.
O 2) the absence of a cytoplasmic membrane.
O 3) the absence of a cell wall.
