have ingested caffeine that day making the tests unfair‚ I will use Daphnia‚ a crustacean. They have on contact with caffeine making it fair. It will be easier to observe as it has a translucent body‚ making it able to see the heart beating under a microscope. It will be a "blind study" to avoid bias results‚ so everyone will be unaware what the solution consists of. Purpose The purpose of my experiment was to determine how caffeine affected the heart rate of Daphnia. Hypothesis I believe

Enzymes Lab Report Inroduction In this lab we explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions. It helps accelerate reactions by lowering the activation energy‚ which is needed for reactions in cells to progress at a higher rate. Activation energy is the minimum amount of energy needed for a chemical reaction to occur‚ yielding products from a given set of reactants. (Unit 7: Enzymes lab) Products

Name : Andi Nadya Amanda Period : 4 Grade : 11 Enzyme Lab Report Question How heats effect the length of reaction time of an enzyme? Hypothesis I think the heat will make the length of reaction time of an enzyme become slowly. Heat is one of a way to denature the substrate. It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly. Method for Collecting Data First I will record the length of reaction time

Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. In the enzyme lab‚ the effects of concentration‚ temperature and pH on the functionality of the enzyme catalase. The enzyme lab was also about measuring reactions by capturing the oxygen that was generated by the reaction. Materials and Methods: Experiment 1‚ 2‚ & 3 Experiment 1 examined the effects of concentration on catalase activity. Experiment 2 examined the effects of concentration in temperature

separate when seen by microscope. Mounting press was use to mount the specimen to make it suitable for handling at the time of grinding and polishing. Different kind of sand paper was used to grind and make smooth the spacmens and finally polishing cloth with diamond suspension was used to remove the extra scrachs . to diffrantiate the grain boundaries it was etched by nital solution. Finally the first observation was taken made by optical microscope and scanning electron microscope.

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put
