Ostwald T. Avery's experiment was an extension of the works of Griffith's. Griffith's experiment using virulent and avirulent Streptococcus pneumoniae (which had different colony characteristics) proved that it was possible for the heat killed virulent Streptococcus pneumoniae to pass on the genetic information for formation of smooth colonies to avirulent strains. Avery, Mc Leod and Mc Carty conclusively found out that the genetic material responsible for transfer of characteristics between the strains was DNA. This was achieved by incubating the cell lysate of virulent Streptococcus with proteases, RNAses and DNAses separately before mixing it with avirulent strains. It was found that only when the lysate was incubated with DNAses did the transfer of smooth colony formation characteristic from the virulent strain to the avirulent strain fail to occur.

Does the oceanic plate theory provide evidence for continental drift?
Yes
Why did other scientists question the theory of plate tectonics?
At the time when this theory was a-brewing, it was difficult to provide conclusive data and evidence.
How have technologies such as sonar and the GPS been used to provide evidence supporting the theory of plate tectonics?

What theory did the scientists in your timeline provide evidence for?
The cell theory states:Cells are the basic units of structure and function in living things.All living things are composed of cells.All cells are produced from other cells.
What is a homologous structure and what does it show?
== == Homologous provide evidence for evolution because it shows the similarities and how we evolved from the same ancestors
What theory did this scientist provide evidence for?
Cell Theory
What theory did the scientist provide evidence for?
cell theory
What can be purchased from Averys of Bristol?
Averys of Bristol, are fine wine merchants since 1793, sell fine wine to anybody in the world. They provide customers with the finest of their high-quality wine.

Fossil evidence rocks and the shape of continents provide support for the theory of?
Plate t
How does the explosion of a nuclear bomb provide evidence of the theory of relativity?
Bomb produces energy in accordance with E=mc^2, which is part of the theory of relativity

Why is the experiment important?
In physics, experiments are mostly used to provide proof of a theory. For example, when a theory predicts a particular relation between an object, its placement, and the time it takes to fall to the floor, a series of experiments can be conducted to provide evidence for the theory, or to dismiss it.
Did Alfred Wegner provide evidence from land forms and climate in support of his theory of the shrinking Earth?
Alfred Wegner developed the theory of plate tectonics, not a theory of a shrinking Earth. The Earth is not shrinking and no scientific theory has ever proposed that it is.
What theory did the scientists in your timeline provide evidence for?
The cell theory states:Cells are the basic units of structure and function in living things.All living things are composed of cells.All cells are produced from other cells.
Evidence that supports the theory of evolution is called?
"Evidence". There's no special term to distinguish evidence supporting one theory in science from evidence supporting any other theory in science.
