SUMMARY:

          Dr.Renquist is a doctor at the University of Arizona in the department of Animal Comparative Biomedical Sciences (ACBS). Dr. Renquist first started writing this while earning his Master’s Degree.                                                                                                                           

This article is about the injection of Selenium into the bodies of fifty - five lady cows or heifers. Dr. Renquist and his team injected many amounts of Selenium into the blood for more than 365 days. They had also divided the cows into three separate teams; A, B, and C. Each day one member of the team recorded just how much the blood pressure rose and lowered. The team made sure before the experiment if the cows had diseases or sickness, they had also checked to make sure the cows weren’t pregnant.               

                   

 During the experiment Dr. Renquist talks about many math equations they had used to get certain results. The main concentration was set on Selenium growth in the blood. Dr. Renquist and his team were definitely satisfied with the results of the experiment as the level of Selenium in the blood was rather high.                                                      

       I.         1)   Does Selenium affect the way the cow body works?

    II.          2)  How many members were in his team?

 III.            3)How high would the blood level of Selenium be if you were still going? Would the heifers live?
