Answer:
As a result of the Hershey and Chase experiments, scientists believe
that the “transforming principle” is DNA.
Explanation:
Hershey and Chase determined that DNA, not protein, was the inherent material. They resolute that a defensive protein coat was molded everywhere the bacteriophage, but that the interior DNA is what discussed its capability to produce offspring inside a bacterium. Transformation occurs when one bacterium picks up free-floating DNA and incorporates it into its own genome. When scientists first observed this behavior, it seemed that genes were transforming one type of bacteria into another, so they concluded there must be a 'transforming principle' at work.
Answer:
Fungi
Explanation:
Fungi are an example of saprotrophs i.e. organisms who live and feed on dead organic matter. Saprotrophic nutrition is described as chemoheterotrophic extracellular digestion. It involves the extracellular release of digestive enzymes on the organic matter. The enzymes break down the organic matter into a simpler form, which is then absorbed by the fungus.
