Fly Lab Shannon Ladd Introduction: Famers and herders have been selectively breeding their plans and animals to produce more useful hybrids for thousands of years. It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown. Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. A contributing geneticist named Gregor Mendel (1822-1884)‚ discovered through

Synthetic‚ Structural‚ theoretical and biological study of triorganotin(IV) Schiff base complexes derived from amino acids Abstract A new series of triorganotin(IV) complexes of monofunctional bidentate Schiff base have been synthesized and characterized through elemental analysis‚ conductance measurements‚ molecular weight determinations‚ UV-visible‚ multinuclear (1H‚ 13C‚ 119Sn) NMR spectroscopy‚ FT-IR‚ X-ray powder diffraction and theoretical calculations. On the basis of these techniques‚ it

Job Safety Analysis or Job Hazard Analysis All employers have duty of care to individuals‚ staff‚ contractors or third parties in the workplace. It is also a legal requirement that organizations should document any health and safety risks that have been identified in the workplace. Equally‚ it is necessary to record the actions taken to reduce those risks What is a Job Safety Analysis or Job Hazard Analysis? One way to increase the knowledge of hazards in the workplace is to conduct

Effect of enzyme concentration on rate of reaction Research question: is there a relationship between catalase concentration and the rate of reaction? Hypotheses: if the enzyme concentration is increased then the rate of reaction will increase. If the enzyme concentration is decreased then the rate of reaction will decrease. Controlled: temperature Independent: % catalyze concentration ( Dependent: rate of reaction (mm/s) Materials: Mortar and pestle Graduated cylinder Distilled

introduction‚ Gauge assumed that either tryptophan negative‚ or weak tryptophan positive genes would survive in a tryptophan-free environment. Gauge was proved correct when one of the E.coli strains carrying the mutated tryptophan gene was unable to grow. However‚ one of the mutated E.coli genes was proved to be weakly tryptophan producing and appeared only one week after inoculation. This result showed that the E.coli bacteria are able to survive under low tryptophan conditions. With this result‚ Gauge

Purpose: The purpose of this lab is to determine the effect of additional mass added to a cart’s existing mass‚ without changing the applied force‚ on the acceleration of the cart. We will test this effect by hanging a constant mass to a cart and use a computer program‚ LoggerPro‚ to calculate the acceleration which is expressed through the slope of the graph. The cart’s initial mass is 500 grams which we change by adding more weights in order to see a difference
