The Microscope Lab Brandy Talley PRCC Biology Lab Online June 13‚ 2013 Purpose: The purpose of this lab is to learn about different types of microscopes that we use today‚ learn the parts of the microscope‚ and how to properly use a microscope by exploring various slides. Materials: *Microscope *Letter “e” slide *Onion root slide *Bacterial capsule slide *Cheek smear slide Lab Notes: 1.What is the difference between a compound

happens between an analyte and a titrant. A redox titration is done just as a normal titration is done‚ however instead of titrating an acid against a base‚ an oxidizing agent is titrated against a reducing agent and the equivalence point is reached when the reducing agent is completely oxidized by the oxidizing agent. (Chang‚ 2011). An indicator is used just as in an acid-base titration‚ although in this experiment because of its self-indicating property KMnO4 the titrant‚ it is also used as indicate

Biofuel Enzyme Kit Katie Adamson Biochemistry Laboratory‚ BIO124L 1/29/15 Abstract The objective in this lab was to determine the effects different conditions had on the enzyme cellobiase. We examined reaction rates in the presence or absence of an enzyme‚ the effects temperature and pH changes on the enzyme and the effects enzyme concentration and substrate concentration had on the enzyme. As expected results showed us that cellobiase works optimally when conditions are favorable. We see this

The Gene Lab 1. Introduction The purpose of this report is to inform dog breeders of a very common genetic disease known as Progressive retinal atrophy (PRA). The report will also inform buyers of the disease so they are aware of the disorder and they can check to dog’s pedigree for the disease. PRA could affect any dog‚ as a result of this it is recommended that the offspring should be examined by a board-certified veterinary ophthalmologist and screened for the existence of the disorder.

baking Yeast helps raise the dough and also yeast is used in the process of making wine.The Reason why yeast was chosen to was to see how yeast can metabolize different sugars and how much Co2 they release when when metabolizing.To test the yeast at the lab we used 4 different types of carbohydrates which are known as Glucose‚Lactose‚Sucrose‚and Starch.The main thing that make some of these carbohydrates different from each other is if it’s a Monosaccharide‚ Disaccharide‚or Polysaccharide.

Ketchup Lab Report Problem: People visiting fast food restaurants complained that ketchup was dripping onto their fingers and clothes. What could we do to insure that the ketchup will not drop all over the customers? Hypothesis: If I put one ketchup packet in a hotter bath then it will move faster down the styrofoam plate. Independent Variable: The temperature Dependent Variable: The viscosity of the ketchup’s “runniness” Constants: The type of ketchup

Being able to identify unknowns is important in chemistry because it allows chemists to identify what chemicals they are working with if they have been improperly labeled or if they are trying to determine substances in a compound. Molecular weight and pKa are two properties that help to identify unknown compounds. To find the pKa of an unknown‚ pH meters are used during titrations to measure the potential difference in a solution by measure the difference of hydrogen-ion activity in a solution and
