Organic Lab 2 February 14‚ 2009 Experiment 4: Borohydride Reduction of 2-Methylcyclohexanone Introduction: When learning about reduction reactions‚ we know that the addition of nucleophilic hydride anion (H-) to the carbonyl group will in turn result in the reduction of aldehydes to primary alcohols. Borohydride‚ and Lithuim aluminum hydride are commonly used as reducing agents. We can note that both of these reagents have a (H-) anion‚ hence it will be a powerful base and also take the

With the exception of catalytic RNA molecules‚ or ribozymes‚ enzymes are proteins. The ability to assay the activity of specific enzymes in blood‚ other tissue fluids‚ or cell extracts aids in the diagnosis and prognosis of disease.

Water Transport in Plants Introduction In this lab experiment‚ we set out to examine the different transpiration rates of a plant system in certain environments. Water is transported in a plant by the process of transpiration‚ which is the loss of water through evaporation from the surface of leaves. The stomata in leaves are responsible for the diffusion of water vapor. Transpiration brings water upward through the xylem in the plant. There are certain factors that can affect transpiration

Foreign studies and literature Studies about Family income or Socioeconomic status of the family reveals that there is an increased of number of the students who got pregnant during college days. According to (Wolfinger 2008)‚ the people from impoverished families often pregnant at an early age because they lack alternatives‚ such as opportunity for higher education. Socioeconomic status that does not provide any alternative to young girls directs them to early pregnancy. Similarly‚ (Ono 2008)

Physio-EX Blood Analysis: Computer Simulation Introduction In this lab five blood tests will be performed: hematocrit determination‚ erythrocyte sedimentation rate‚ hemoglobin determination‚ blood typing‚ and total cholesterol determination. A “hematocrit refers to the percentage of red blood cells (RBC’s) in a sample of whole blood. Since the function of red blood cells is the transport of oxygen to the cells of the body‚ the higher the hematocrit‚ the more red blood cells are available to carry
