Well a hypothesis is guess about an experiment and how it works or is preformed. If your supporting one then you agree with how its done and how it works and you got good results. If you fail a hypothesis that means you most likely tried and didn't succeed or didn't get the results you wanted. Sorry if this is confusing the question kinda confused me.
QRS complex refers to the combination of the Q, R, and S waves, and indicates ventricular depolarization and contraction (ventricular systole).
Ventricular rate can be calculated by determining the time interval between QRS complexes. The duration of the QRS complex is normally 0.06 to 0.10 seconds. This relatively short duration indicates that ventricular depolarization normally occurs very rapidly.
P QRS and T waves in electrocardiogram signifies the P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization.

Botulism can easily be prevented by boiling food prior to consumption.
<h3>What is Botulism?</h3>
Botulism may be defined as an imperative food poisoning that is provoked by botulinum toxin delivered in food by a bacterial species clostridium botulinum.
Clostridium botulinum inhibits the release of acetylcholine in the neuromuscular junction and causes defects in sensory perception through the central nervous system.
It can only be prevented by taking the proper boiled food prior to consumption.
The complete question is as follows:
- boiling food prior to consumption.
- administering antibiotics to patients.
- not eating canned food.
- filtering food.
- preventing fecal contamination of food.
Therefore, the correct option for this question is A, i.e. boiling food prior to consumption.
