Which of the following regarding antimicrobial control agents is FALSE?Select one:a. Contaminating organic debris such as blood or sputum decrease effectiveness. b. Silver is used for treating antibiotic-resistant bacteria. c. Some agents inactivate viruses by attacking cell membrane lipids. d. Some agents kill by denaturing microbial cell proteins. e. Some agents affect microbial cell membranes by dissolving lipids.

C) Some agents inactivate viruses by attacking cell membrane lipids

Explanation: Viruses have machinery in them to replicate and survive thereby making them resistant to antimicrobial control agents. They are not easily inactivated by antimicrobial control agents.

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.
