John tyndall and Ferdinand Cohn discovered that there were two types of bacteria exisitng in nature: those who are affected by heat leading eventually to their demise and those that are resistant or immune to a certain degree of heat. This finding is important in the devising of the sterilization process which it was recognized as a method of killing bacteria by applying heat to the medium. Later on, Cohn discovered the existence of endospores. Today, there are various types of bacteria, the thermobacteria, the cryobacteria- bacteria that are prone to cold temperatures and the bacteria that thrive on temperatures from 30-35 degrees normally.

Explain the reason why Canada is thinly populated although it is the second largest country in the world.
Ket [755]

Weather will be the primary reason. Despite its huge size. the real habitable area is probably less than 10% of its geographical size. Even Southern Ontario is deemed by many I know to be "too cold to live". 90% of Ontario and Quebec are simply inhabitable. I also personally think the entire Manitoba and Saskachewan are not suitable for human habitation unless we can create a way to simply hibernate during the 6 month winter (why there are so few people in Montana and North Dakota?) The fact that Montreal are thrive as a vibrant metropolis is already sort of a miracle and we don't see many such large cities with such severe weather. The only other case I can think of is probably Moscow.
