Food borne illnesses

Food borne illnesses are formed by the ingestion of foods contaminated with pathogenic microorganisms. The contamination of food may occur at any stage in the process from food production to consumption. Food infection and food intoxication are the two types of diseases which arise from pathogenic microorganisms. The severity of the foodborne illness depends on the type of pathogenic microorganism or toxin ingested, the quantity of the contaminated food consumed, and the health status of the individual.

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.
