<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
Explanation:
Dinosaurs are living organisms that depends on the environment for survival. As the asteroid hits the Yucatan Peninsula area about 66 million years a couple of things can happen:
Frictional heating of the surface as the earth collided with the asteroid. This heating will cause surface temperature to rise globally and can induce the phenomenon of global warming. This can lead to release of water from reservoirs on the earth surface and hence flooding.
The impact can lead to increase in surface pressure beyond normal and that which life has adjusted to.
Debris in form of dust will be released into the atmosphere and a global air pollution will occur. Gases useful for life will be highly polluted by the vast amount of dusts and other particles discharged into the atmosphere.
