whether the metal bonded to a Sulfur atom or an Oxygen atom of the DMSO. After analyzing the IR spectrum‚ it was determined that S=O shifted to a lower wavenumber in CuCl2~2DMSO and that S=O shifted to a higher wavenumber in RuCl2~4DMSO. Introduction Depending on the metal‚ it will bond to DMSO through its oxygen or sulfur atom. This will cause the frequency of the S=O bond absorption to move depending on which atom it bonds to. For oxygen bond the frequency will be low due to the weakened interaction

so the skeletal muscle cells are supplied with more oxygen and respiratory substrates used to generate energy in respiration where it is needed. A drug that increases heart rate is called a positive chronotrope‚ and this is demonstrated in this experiment when adrenaline is used to increase heart rate in Daphnia. One of the ways adrenaline increases heart rate is through the action of what is known as a ’second messenger ’ or ’transduction component ’‚ in this case it is a chemical made in the

What is the nature of obedience? A question that two leading scientists of the 1960’s tried to answer. At the heart of the cycle of enquiry stands Stanley Milgram with his initial experiment on obedience performed in 1963. The research results were so notorious that it determined scientists like Charles Hofling to replicate the study‚ and in 1966‚ he completed a conceptual replication of Milgram’s experiment. First we will look at how the two studies explore a similar topic using a different design

1930’s six hundred African American men were lied to and left to die while under the care of doctors and scientist thinking that they were being taken care of. The men participated in an experiment called the Tuskegee syphilis Experiment were the men would partake in a medical study. This paper will examine how scientist took advantage of the men who participated in this experiment and neglected to tell them the truth. This topic really interest me because it took 40 years into the experiment to see

On April 5 1968 Jane Elliot preformed the famous experiment in her classroom separating blue-eyed and brown-eyed students. She had separated them by making one eye group inferior to the other making them have certain benefits and better treatment than the other. Then it was

Meselson–Stahl experiment From Wikipedia‚ the free encyclopedia The Meselson–Stahl experiment was an experiment by Matthew Meselson and Franklin Stahl in 1958 which supported the hypothesis that DNA replication was semiconservative. In semiconservative replication‚ when the double stranded DNA helix is replicated each of the two new double-stranded DNA helices consisted of one strand from the original helix and one newly synthesized. It has been called "the most beautiful experiment in biology.[1]"

In the experiment‚ a group of young men were shown a line with three other lines of various lengths next to it‚ and asked to determine which of three lines matched the length of the first line. There was‚ however‚ a catch: all but one of the men were
