Who discovered that dna was the genetic material or transforming factor that could convert nonvirulent r-type streptococcus pneu
KatRina [158]
Discovery
               In 1928 it was discovered by Frederick Griffith in an experiment generally known as transformation.

Experiment
                 
 In his experiment he considered two strains of <em>streptococus pneumonia,</em> one was R-type which was non-virulent and cause no disease in mice, other was virulent and S-type which cause disease and at last death of mice.
This experiment was comprised of four steps which are as follow:

 Step 1:
           First he injected living strain of S into mice, after sometime mouce died.

Step 2:
          He injected living strain of R into mice, the mice alive as he did not got any disease.

Step 3:
         He injected heat killed strain of S into mice and mice remain alive.

Step 4:
           He mixed living R strain with heat killed S strain and then inject into mice. As a result the mice died.

Conclusion:
                  It was found that genetic material from heat killed S stain were transferred to living R (non-virulent) strain, as a result R become virulent and cause the death of mice.

Why does a compressed air can become extremly cold when you use it?
BartSMP [9]

Answer:

The reason the compressed air gets cold after being used is due to a process known as adiabatic cooling, a property of thermodynamics. A gas, initially at high pressure, cools significantly when that pressure is released. The compression needed to turn a gas to liquid allows a large amount of gas to fit in a relatively small space, and when that gas is released to a large space, it rapidly expands to fill the space.
