Roy Levin Bio 11 Lab Dr.Izquierdo Analysis of Macromolecules in Tissue Homogenates of Bos taurusMaterials and Methods The homogenates provided were made by homogenizing tissues in a sucrose phosphate buffer in a 1:20 ratio. The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

When we started this lab the question (subject) we had to try and solve was ‘Which pattern of inheritance is present in the O’Smithsteinskis and AkimGarciaChan family pedigree? If when looking at the number of people shaded in our pedigree and find that the number is increasing each generationon then we can assume that the p

Multimedia Graphic Bell Labs: A Hive of Invention But we idealize America’s present culture of innovation too much. In fact‚ our trailblazing digital firms may not be the hothouse environments for creativity we might think. I find myself arriving at these doubts after spending five years looking at the innovative process at Bell Labs‚ the onetime research and development organization of the country’s formerly monopolistic telephone company‚ AT&T. Why study Bell Labs? It offers a number of lessons

Lab Report 7: Analysis of Cereal Introduction: The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze

simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration for kinematically restricted motions‚ which will discover. An adjustable slider-crank apparatus

During this experiment(Muscle fatigue lab) it will be seen that after a while of squeezing a small ball there won’t be the same amount of energy that was started with first and you will feel a burn in your arms which makes you feel hurt and don’t do a lot of squeezing; which is called the
