How is it that some bacteria live in the hot springs of Yellowstone Park at temperature up as high as 73 C?
Extreme thermophiles have adapted unique ways to surviving harsh conditions. They're enzymes are specially designed to resist denaturing at high temperatures. What's really amazing is their DNA. Extremophile DNA is positively supercoiled (this describes the way it is twisted around itself) which makes it harder to separate the strands. DNA in most other species is negatively supercoiled (meaning it's wound up on itself in the opposite direction as positively supercoiled DNA). Since DNA is the building block of life, it makes sense that you need to be able to protect it from the environment. Extremophiles do just that by positively supercoiling it. It is much more resistant to heat denaturing than other DNA would be, which helps the bacteria to survive.
High temperatures will kill the bacteria in the food, although it wont kill all bacteria just enough that it is healthy to eat
When bacteria is subjected to high temperature, they will die just as you would.
It kills the bacteria.
you pee in it
Sterilizing I think. You kill any bacteria with heat or radiation.
The mice injected with mixture died
15.000.000 Celsius
Archeabacteria are the most simple celled organisms. they can thrive in hazardous regions because they are so simple. being simple allows them to live in such harsh regions like high salt concentrations, high heat and high pressured areas. they are the simplest form of prokaryotes (bacteria are also prokaryotes).
Heat can kill flu or cold bacteria. However, the heat has to be high enough. Different viruses and bacteria have different heat tolerances. Some can survive temperatures of over 250 degrees Fahrenheit.

The live R bacteria acquired a capsule and became live, virulent S bacteria.
Yes, excessive heat can kill the bacteria in buttermilk.
becouse we have bacteria that called hyperthermophiles organism thar can live at very high temp (80 c ) also we have thermophiles ...organism are heat lover they can live at temp (50-60)
Heat killed S bacteria in Griffith's experiment was because of the temperature of the heat. The heat was high enough to kill many things like proteins and enzymes, so the bacteria could not create endospores to harm the immune system.
Frederick Griffith hypothesized that live, harmless bacteria and the heat-killed bacteria were mixed, some factor was transferred from the heat-killed cells into the live cells! it has nothing to do with bats flying thru walls!!
The mice injected with mixture died
that it was very gay
15.000.000 Celsius
Because heat destroys bacteria. Heating an object to high temperature kills of harmful organisms.
It means that their brains have been processed with high heat to keep out the bacteria.
Bacteria CAN live on Earth.
