Answer:
The three experiments are:
Griffith performed an experiment by which he observed that harmless R strain of the bacteria transformed into harmful S strain when mixed with heat-killed S strain.
He concluded that the "transforming principle" from the heat-killed S strain bacteria transformed the R strain.
- Avery, McCarty, and MacLeod- Identification of transforming principle
They identified that the nature of the transforming principle mentioned by Griffith.
They used digestive enzymes such as proteases, RNase, and DNase.
They conclude that the transforming principle was DNA in nature.
- The Hershey-Chase experiment
They used radioactive sulfur to label proteins and radioactive phosphorus to label DNA in the bacteriophage.
The infected bacteria were blended and centrifuged.
The radioactive phosphorus, that is, DNA was found inside the cell whereas the radioactive sulfur, that is, proteins were found outside the cell.
It also proved that the genetic material was DNA, not protein or RNA.
Answer:
thru the nucleus or cell wall i think
Explanation:
Answer:
Probability is the term you seek.
The population size of a predator species is directly controlled by the population size of it's prey. If the predator has no prey the population size will go down because they have no food.
Answer - A. Deep because there is less O2 exchange
Reasoning - Bacteria has been known to only use half a percentage which is .5 percent of O2.
