10 Questions
Where can bacteria be found?
Bacteria can be found in soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust.
What are bacteria?
Bacteria are mostly free-living organisms often consisting of one biological cell.
What is the study of bacteria known as?
The study of bacteria is known as bacteriology, a branch of microbiology.
What role do bacteria play in the nutrient cycle?
Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and the fixation of nitrogen from the atmosphere.

What are antiarrhythmic agents used for?
Antiarrhythmic agents are used to suppress abnormally fast rhythms, such as atrial fibrillation, supraventricular tachycardia, and ventricular tachycardia.
How many phases is the cardiac myocyte action potential divided into?
The cardiac myocyte action potential is divided into 5 phases.
Who introduced the Vaughan Williams classification?
The Vaughan Williams classification was introduced by Miles Vaughan Williams.
What does the sharp rise in voltage ('0') of the action potential correspond to?
The sharp rise in voltage ('0') corresponds to the influx of sodium ions.
Why is the classification of antiarrhythmic agents considered imprecise?
The classification of antiarrhythmic agents is considered imprecise because many of the agents have multiple modes of action.
