(Ashburner‚ M.‚ Golic‚ KG et al‚ 2005) Drosophila melanogaster was used in this experiment‚ in order to: 1) demonstrate the law of segregation in recessive alleles‚ example: dumpy and sepia are recessive alleles‚ i.e. the phenotype will only be expressed if the fly is homozygous for the allele‚ as the heterozygotes are indistinguishable from the homozygous wild type form showing that the wild type strain of the allele is dominant; 2) as well as to demonstrate the law of independent

The refraction of light lab used common materials to examine the process of the refraction of light. The title of this lab is exactly what occurs throughout the four different experiments. All four parts of this lab use prior knowledge to observe the complex concept of refraction. Refraction is the bending of a light when it enters a medium where the speed of light is different. When light enters through the glass and water the speed of light becomes decreased. This is due to the density of water

eye colour. Located on the X chromosome‚ a fruit fly can exhibit the phenotype white eye (homozygous recessive)‚ or red eyed wild-type (dominant). Males of the species are XY‚ and as such only carry one eye colour determining X chromosome. Females are XX‚ and can therefore carry two eye colour determining genes. A heterozygous female will always display the dominant wild-type gene if present. The uncertainty of female genotype is cleared by the acquisition of an F0 stock which is homozygous dominant

Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules

Christine Rosen’s essay makes a brilliant point that social networking sites have become the modern equivalent of a self portrait. People post the pictures they want others to see and information that may be flattering to themselves all in order to create a façade to boost their image. The development of social network sites have not just appeared over night; their origins began with a low tech bulletin board system called WELL which was launched in the 1980s but with the years to come more networking
