Why did Hershey and Chase grow viruses in cultures that contained both radioactive Sulfur. What might have happened if they had used only one radioactive substance.?

Radioactive sulfur and phosphorous. Proteins contain sulfur, but no phosphorous. Nucleic acids contain phosphorous, but no sulfur. The T even phages they used were nucleic acid enclosed in a capsid of protein. So, to label them radioactively told them by experiment which substance, nucleic acid or protein, was the generic material.
To only use one radioactive substance would have been useless in telling which was the genetic material. Google Hersey and Chase for more detail.

What is nuclear energy and what are the positive and negative impacts on the world?
Nuclear energy is nearly the same as coal energy, in that they both use heat to boil water and use the vapour from this to spin turbines creating electricity. The difference is that they us different heat sources. In nuclear energy, the heat source is radioactive elements. Radioactive materials have chemical reactions which in the process create a lot of energy, mostly heat.The ways it negatively affects us are simple. First of all when they are done with radioactive elements, they have to dispose of the waste byproducts. So they put them in lead barrels and bury them. The waste is not producing heat, but is still radioactive; so if it leaks it could cause heaps of damage. The other reason we might be negatively affected is if an accident happened...think about Chernobyl or more recently Japan.Other than that nuclear energy is a really clean, efficient and useful energy source, as opposed to coal.
