Experiment #1 (griffith): you inject mice with a strain of "smooth bacteria. a few days later you find that the
mice have died from pneumonia. you inject different mice with "rough bacteria and find that they all survive.
next, you heat the disease-causing smooth bacteria and then find that all of the mice survive. explain why.
you then decide to heat-kill the disease-causing smooth bacteria and mix them with live harmless rough
bacteria. you inject mice with the live bacteria from the mixture and find that the mice die of pneumonia. you
culture the bacteria to find that there are now live disease-causing smooth bacteria. how do you explain this?

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
