Answer: a. True
Explanation: These postulates were formulated by Robert Koch as a result of his experiments with healthy and infected mice. The postulates are often used to determine if a phatogen causes a disease. These are:
- The pathogen must be present in sick individuals but not in healthy ones.
- The pathogen must be isolated from individuals and cultivated in a pure culture.
- The pathogen cultivated must cause sickness when it's injected in suceptible inviduals.
- The pathogen must be isolated from the injected individuals and must be exactly as the first one.
Bacteria have been found to be able to detoxify certain chemicals; perhaps there are more.
<h3>What is bacteria?</h3>
Bacteria are common, primarily free-living creatures with only occasionally one biological cell. Bacterium is the singular form. They account for a large chunk of the prokaryotic microbial kingdom. The bulk of the ecosystems on Earth are home to bacteria, which are typically a few micrometers long and were among the first life forms to emerge there.
Bacteria can be found in soil, water, acidic hot springs, radioactive waste, and the deep biosphere of the Earth's crust. Bacteria play a crucial role in several stages of the nutrition cycle by recycling nutrients like nitrogen from the atmosphere. The nutrient cycle includes the breakdown of dead bodies; microorganisms are in charge of the putrefaction stage of this process.

Sympathetic nervous system
The neuron, a cell that composes the nervous system. For example a brain, an organ composed of thousands of neural fibers and glial cells that performs many important organismic functions. </span>
<span>Neurons are specialised cells that have dendrites, axons and terminal buttons that sends and receives stimuli from the environment and transduces it into a meaningful information and understand the complexities which the brain now functions.<span>
