Microscope lab report Introduction Microscope is a tool used to enlarge images of small objects that are hard to study with bare eyes. The compound light microscope‚ which is going to be used in this lab activity‚ is an instrument with two lenses and various knobs to focus the image. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives: •Demonstrate the appropriate procedures used while using the compound light microscope correctly. •Make and use a wet mount

‚ saliva and hydrochloric acid was used in the second test. The enzyme involed in this test is salivary amylase which can found in saliva. Salivary Amylase‚ is called ptyalin it’s to break down starch to sugar. Things we ate is broken down in mouth by amylase. Amylase hydrolysed starch into a reducing sugar which can give beneduct test a positive result. Body temperature is the optimal temperature for the action of amylase. Enzymes are catalysts for any reactions. They provide an alternative way

Lactase is an enzyme that splits up the disaccharide lactose into monosaccharides glucose and galactose‚ but its function diminishes with age resulting in a wide use of lactase supplements. This enzyme functions under specific conditions‚ so we investigated the effect different salt concentrations have on the enzyme activity. Serial dilutions were performed to prepare a lactase solution as well as twenty percent‚ fifteen percent‚ and five percent concentrations of NaCl. Three different treatments

At what price did you eventually trade? 12 Your surplus: -1 2b) If you didn’t trade‚ why not? Economic Relevance 3. What is the predicted equilibrium? How does the most common trading price in your lab session compare to the equilibrium price? The predicted equilibrium was (13‚ 7). 4. Who was able to stay in the market? Who was shut out?

INTRODUCTION: An enzyme is a substance that in most situations‚ is a catalyst‚ which increases the rate of reaction by contributing alternative reaction pathways of lower activation energy. Enzymes are able to do this by binding to reactant molecules and allowing them to cooperate in a more energy efficient way. If catalyzed by the appropriate enzyme‚ reactions that would take an extreme amount of time would rather occur in fractions of a second. First‚ enzymes increase the rate at which chemical

The human cardiovascular system consists of the heart‚ the blood‚ and a system of transporting vessels. A human heart has four chambers: a right and left atrium and a right and left ventricle. The fist-sized heart sits in its own sac (the pericardium) in the middle of the chest under the sternum. In most people‚ the apex of the heart points to the left. There are two circuits of simultaneous blood flow in humans: a pulmonary circuit and a systemic circuit. In the pulmonary circuit‚ the right

Hoeung 1 Tiffany Hoeung Ms. Braceras Honors Earth Science 4 March 2015 How Does Slope Affect the Movement of a Glacier Purpose: The purpose of this lab was to find how slope would affect glacier’s movement‚ and whether the movement was at a constant rate or changed. Hypothesis: If the slope is more steep‚ then the glacier’s movements will be faster than a less steep slope. Materials: Flubber Glue Water Borax Long tray Timer Procedure: 1

Enzyme activity The introduction is a statement of the subject and objectives of the experiment and presents your hypothesis. Relevant background information (appropriately referenced) is given in sufficient detail that a person unfamiliar with the topic can understand the nature of the experiment. A good introduction is clear and concise. Carbohydrates and proteins should be explained in terms of their structure and major functions in cells. Your intro should end with a brief overview of the amylase

9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚
