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

Kidneys * Kidneys maintain the purity and constancy of our in internal fluids. Every day‚ the kidneys filter gallons of fluid from the bloodstream. They then process this filtrate‚ allowing wastes and excess ions to leave the body in urine while returning needed substances to the blood in just the right proportions. Kidneys also regulate the blood’s volume and chemical makeup so that the proper balance between water and salts and between acids and bases is maintained. * The Kidneys alone

Renaissance‚ scientists and doctors were only exposed to inaccurate anatomical knowledge from centuries ago due to the lack of human dissections. Galen was one of these anatomists from awhile ago‚ more specifically Rome in the first century. His beliefs were worshipped for 14 centuries‚ up until the Renaissance. Before the Renaissance‚ the church didn’t allow human dissections‚ which affected doctor’s abilities to learn about the human body. Animal bodies were their only source of anatomical knowledge
