There is a common thought that hot water freezes faster than cold water. Develop a strategy to investigate this theory. Construct a well thought out question and a testable hypothesis. Write a justification for your hypothesis; for instance, if you hypothesize that cold water freezes faster than hot water, include an explanation as to why you believe this to be true. Come up with an experimental design to test your hypothesis. Include an explanation of how the data you collect will be able to support or disprove the hypothesis.

Imagine you are a student in alfred hershey and martha chase's lab in the late 1940's. you are given five test tubes with the e. coli bacteria that were infected with t2 bacteriophage that have been labeled with 32p or 35s. unfortunately, you forgot to label the tubes and are now uncertain which were 32p labeled and which were 35s labeled. you place the contents of each tube in a blender and pulse it for a few seconds to shear off the protein coats from the bacterial outer membranes. you then centrifuge the contents to seperate the protein coats and the bacterial cells. you then check for radioactivity and obtain the results shown below. which tubes contained e. coli infected with the phage labeled with 32p? select all tubes that apply.
