The major contribution made by Avery, MacLeod, and McCarty was 'transformation of nonvirulent cells with a DNA extract was blocked only if DNase was added'. This observation supported the idea that the transforming agent in Griffith's experiment was DNA.
The Avery–MacLeod–McCarty experiment showed that DNA was the transforming agent observed in Griffith's experiment.
Griffith's experiment (1928) suggested that bacteria were capable of transferring genetic information (DNA) by a process of horizontal gene transfer called transformation.
While the bacteria were killed by heat, Frederick Griffith observed that the DNA had was taken up by II-R strain bacteria via transformation.
Avery–MacLeod–McCarty experiment observed that protease enzymes did not destroy the transforming agent (but DNAse destroyed this transforming principle), thereby suggesting that the transforming agent in Griffith's experiment was bacterial DNA.

Answer:
Therefore,when carbon monoxide is present,it blind to hemoglobin preferentially over oxygn.As a result,oxygen cannot blind to hemoglobin ,so very little oxygen is transported through the body carbon monoxide is a colorless odorless gas and is therefore difficult detect.
It makes a longitudinal wave because it stretches and compresses while it slithers forward
<span>A sequence of organisms through which energy is transferred, beginning with the primary producer, is a "Food Chain"
