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.

What is the name of the process for killing bacteria with high heat?
Sterilizing I think. You kill any bacteria with heat or radiation.
What effect did an injection of live R bacteria mixed with heat killed S bacteria have on the mice?
The mice injected with mixture died
How much is the highest degree of heat in which gram negative bacteria could live?
15.000.000 Celsius
Are Archeabacteria simple or complex celled?
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).
What kills flu virus cold weather or hot weather?
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.
What is the name of the process for killing bacteria with high heat?
Sterilizing I think. You kill any bacteria with heat or radiation.
Why was the mixture of heat killed s bacteria and r bacteria virulent?
The live R bacteria acquired a capsule and became live, virulent S bacteria.
Does heat kill the live cultures in buttermilk?
Yes, excessive heat can kill the bacteria in buttermilk.
Why doesn't the 48 to 50 C temperature of the melted agar kill most of the bacteria?
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)
Why did heat kill Griffith's S bacteria?
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.
What is Fredderick Griffith hypothesis?
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!!
What effect did an injection of live R bacteria mixed with heat killed S bacteria have on the mice?
The mice injected with mixture died
What happened when Griffith injected mice with a mixture of heat-killed pneumonia-causing bacteria and live bacteria of the harmless type?
that it was very gay
How much is the highest degree of heat in which gram negative bacteria could live?
15.000.000 Celsius
Why is heat used to sterilize nonliving objects?
Because heat destroys bacteria. Heating an object to high temperature kills of harmful organisms.
What does it mean that the us is idealogically homogeneous?
It means that their brains have been processed with high heat to keep out the bacteria.
Why are bacteria unable to live on earth?
Bacteria CAN live on Earth.
