<u>Answer:</u>
Discovery of vaccine for smallpox, viruses and actual organisms that cause many diseases lead to the development of Germ Theory.
<u>Explanation:</u>
- Theory was the 'predominant theory' of 'disease transmission' before germ theory but it is no longer accepted as a 'scientific theory' of diseases.
- 'Formal and reliable experiments' on germs and diseases relationship were 'conducted by Louis Pasteur'.
- He showed that growth of microorganisms was not a spontaneous generation and his pasteurization experiment provided key pieces of evidence that supported germ theory.
In humans, the maintenance of a stable internal temperature is a direct result of Homeostasis. Homeostasis is the ability of the body to maintain an equilibrium condition within it's internal environment even when dealing external changes. Homeostasis happens in human when there is an effort exerts by the body to regulate it's internal temperature around 98.6 degrees Fahrenheit. For example, during summer days we produce sweat for our body to cool off, and during winter we shiver for our body to produce heat.
Parietal cells produce gastric acid (hydrochloric acid) in response to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors). Parietal cells contain an extensive secretory network (called canaliculi) from which the HCl is secreted by active transport into the stomach.

12) A team of archaeologists excavating a sedimentary rock layer come across some primitive hunting tools used by early humans.
