Physical change only change the appearances of a substance, not it’s chemical composition. Chemical changes cause an entirely new substance with new chemical formula.
<h2>Koch's postulates </h2>
Explanation:
Koch formulated a set of criteria that could be used to identify the pathogen responsible for a specific disease and these criteria came to be known as Koch’s postulates:
The organism must be regularly associated with the disease and its characteristic lesions
The organism must be isolated from the diseased host and grown in culture
The disease must be reproduced when a pure culture of the organism is introduced into a healthy, susceptible host
The same organism must be re-isolated from the experimentally infected host
In the given hypothesis , Koch's postulates could be used as:
1) identify pathogen associated with disease 2) isolate or purify pathogen 3) test subject gets pathogen 4) same disease/ causes liver disease or not
