Answer:
- Fossils are an important part of the study of human evolution When a plant or animal dies its body is acted upon by various forces of nature like wind, air; With time body decomposes and gets covered by layers of soil in millions of years Due to increasing pressure with every layer of soil getting added it creates an impression of the body while it further decays, Even it is acted upon by hot temperature inside So even after millions of years of extinction of a species we can study about it looking at its impression in soil known as Fossil one of the ways is.
Explanation: Hope this helps :)
The prefix of Uni is One or Single. So it would mean having or consisting of a single cell
Another word with the prefix would be unilateral
I think that the answer is B
Answer: Option (B) is the correct answer.
Explanation:
According to Le Chatelier's principle, any disturbance causes in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.
For example, 
When we increase the temperature then the reaction will shift in a direction where there will be decrease in temperature.
This, means that the reaction will shift in the backward direction.
Thus, we can conclude that if the reaction is at equilibrium and the temperature increases, the equilibrium will shift so that there is more nitrogen dioxide.
Melting point- the temperature at which a substance has changed from a solid to a liquid
freezing- the temperature at which a substance chanes from liquid to a solid
boiling point- the temperature at which a substance changes from a liquid to a gas phase
