    • 2 Pages

    Bilirubin is a breakdown end product of heme containing proteins. About 80% of bilirubin is formed from the degradation of erythrocyte hemoglobin after 120 days of erythrocyte life in the blood. The remaining 20% of daily-produced bilirubin is formed from erythrocyte precursors in bone marrow and other heme proteins: myoglobin‚ cytochromes‚ and catalase. Hemoglobin degradation begins with opening of the heme porphyrin ring‚ forming the biliverdin – iron – globin compound known as verdoglobin.

    My results of part B shows that a penny can hold 21 drops of water on the top. This relates to adhesion since the penny that is copper is attracted to a different substance which is water. When the drops hit the penny‚ the adhesive force of the water and the penny keeps the water from falling off the sides.

    Experiment #2 “Density Determinations” Report The objective for experiment #2 was “to determine densities of objects/salt solutions with different concentrations of salt‚ to see how density changes as a function of concentration.” In experiment #2‚ part II‚ calculations of Density of NaCL solutions were made from 0%-25% NaCL concentration. My hypothesis was that as the % increased‚ so would the density‚ because adding weight would increase the density of each solution. The density calculations

For example‚ my ancestors did not overcome their struggle for equality without self-determination to better their lives. Thus‚ their lives have been an inspiration for me. The motivation

    “ A penny for your thoughts” is a saying that isn’t commonly used in my generation‚ but the saying might go away because the government is thinking about taking the penny away. Many people believe the penny is worthless and should be removed‚ and they are right. The penny today rarely gets used and costs more to create the penny then its value. Have you ever looked into a wishing well? Well if you have you would have noticed that people only really throw pennies into the well. Many people only
