greatly affect the resistance. The reasons as to why diamond does not conduct electricity were also found. Aim: To investigate the effect that different factors have on pencil lead (graphite) resistance. The factors tested include‚ pencil lead type (HB‚ 2B...)‚ temperature‚ length and cross-sectional area. Hypothesis: The relationship between length and resistance should show an exponential relationship. The relationship between cross sectional area and resistance should be a power relationship

The force applied and the diameter of the diameter of a hardened steel ball is kept constant while four different specimen blocks namely‚ aluminum‚ brass‚ copper and mild steel are penetrated by the indentation steel ball to create different indentations on each of them. The diameters of the indentions allow us to obtain the Brinell Hardness number to predict the hardest and the softest material among them

invertebrate hemoglobins were called erythrocruorins to distinguish them from functionally similar yet structurally distinct pigments of vertebrate bloods. 1. HEMOCYANINS : Hemocyanins are respiratory proteins in the form of metalloproteins containing two copper atoms that reversibly bind a single oxygen molecule (O2). Oxygenation causes a color change between the colorless deoxygenated form and the blue oxygenated form. Hemocyanins carry oxygen in the hemolymph of most molluscs‚ and some arthropods‚ including

instituting an embargo. In 1971‚ the Chilean people elected a socialist president‚ Salvador Allende. Soon afterward‚ the Chilean government began to expropriate U.S. businesses located in Chile. The primary U.S. business in Chile at this time was copper mining. When U.S.-owned mines were seized‚ in most cases‚ their owners were provided with adequate and prompt compensation. The El

and HbS (defective hemoglobin) have varying frequencies and while the HbS gene is present in populations it is important to understand how Malaria in particular can affect the sickle cell frequency. The way that diseases such as malaria impact the HbS gene may be different than how populations unaffected by malaria are impacted by HbS. What will happen to the sickle cell frequency in the presence of Malaria? Hypothesis: 1: In the presence of malaria‚ the sickle cell allele frequency HbS will
