Which of the following statements is false? a. in the lag phase, cell death exceeds cell division. b. in the death phase, bacterial growth may cease as a result of oxygen and nutrient depletion. c. bacteria typically divide by binary fission, producing two daughter cells. d. the generation time of bacteria may vary from species to species.

a. In the lag phase, cell death exceeds cell division. FALSE

Is the period when the bacteria are adjusting to the environment.

b. In the death phase, bacterial growth may cease as a result of oxygen and nutrient depletion. TRUE

Is characterized by an exponential decrease in the number of living cells.

c. Bacteria typically divide by binary fission, producing two daughter cells. TRUE

This is the most common way of division. The duplicate's DNA and part in half.

d. The generation time of bacteria may vary from species to species. TRUE

As in all species, the generation time will always vary.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
