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:
Primary succession occurs in essentially lifeless areas
Answer:
C
Explanation:
Increased biodiversity helps diminish reliance on one species
The organelle inside the cell that eliminates waste is the lysosome. It contains chemicals that help digest food and worn-out cell parts. <span>When nutrients enter the cell, lysosomes release digestive enzymes to break down the nutrients. If the cell isn't getting enough food, lysosomes will digest other organelles so that the cell does not starve. Lysosomes eliminate worn-out organelles from the cell via the process of autophagy.</span>
