Answer:
As DNA contain phosphorus in its structure in large amount, therefore, Harshey and Chase labeled DNA with radioactive phosphorus and because protein contains some amino acids which have sulfur so they labeled T2 bacteriophage protein with sulfur.
So after that they infected E.coli bacteria with radioactively labeled phages and after centrifugation, they have found that pellet which contains cells is showing the presence of radioactive phosphorus and supernatant which have T2 phage capsid protein showing the presence of radioactive sulfur.
Therefore by labeling viral protein and viral DNA they found that DNA is the genetic material not protein.
Answer:
Humans cannot occupy the lowest levels.
Explanation:
Answer: The reason why pestisides are found in our water is because the government and farmers put some type of chemical on the plants and in the water so animals like worms or bugs dont drink or eat our food and water supply.
Hey there!
Nuclei with a high neutron-to-proton ratio usually undergo a beta emission.
Beta emissions, unlike some other types, is radioactive decay throughout these particles, and can have half lives like other types of exponential (usually) decay. Neutrino, along with <em>beta rays,</em> are coming from, or emitted from the nucleus - hence the name.
Hope this helps!
