Answer:

Hershey Chase  and Griffith experiment supported the same conclusion which was: DNA is the molecular substance of genetic inheritance.

Explanation:

Both experiments have was based on different phenomenon and techniques to prove same conclusion.

Hershey and chase conducted an experiment via bacteriophage which consists to DNA and protein coat that infects bacterial cells. He proved the DNA as genetic material by the help of transduction mechanism (Incorporation of Bacteriophage DNA in to bacterial cells). He used two group of Bacteriophage 1st group of Phage contain radioactively labelled proteins by Sulphur 32 isotope. While 2nd group contain Bacteriophage having P32 labelled DNA to infect Bacterial cells. After the infection, the Reaction tubes subjected to centrifuge and presence of radioactivity was determined in pellet and supernatant. The 1st group show radioactivity in supernatant while 2nd group shows racdioactivity in pellet or bacterial cells.

Griffiths just hypothesized a substance that can be transmitted from dead organism to alive organisms with the help of transformation phenomenon (uptake of Genetic material from the surrounding or environment). He conducted his experiments on <em>Streptococcus pneumonia avirulent and virulent species. </em>By mixing dead virulent species and live avirulent species and injecting into the mice results in the death of an experimental animal. While alone dead virulent species and live avirulent species fail to cause disease in mice.

How might biodiversity in Area 1 change if the new bird species ate small mammals, lizards, and toads?
zmey [24]

Knowing that Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. The ecosystem will change if a new species is introduced to an unfamiliar ecosystem. If a new species of birds were to eat another animal that was supposed to be eaten by another. The food chain of the ecosystem would be changed drastically. Aka, it might make the lizards go extinct, and can possibly become abundant. Aka, overpopulating and creating havoc within the ecosystem. Thus, causing imbalance.
