ml of water and cooking oil into a test tube by shaking it. Then we observed the mixture as it settles for five minutes. We shook the test tube again and took a sample into a slide before it settled. We observed it under the LPO of the compound microscope. ii. We placed cooking oil into a Petri dish‚ and dropped an egg solution into it. We observed it for a formation of a membrane‚ then puncturing it. iii. We placed the evaporated milk in a beaker until it is ¾ full and heat it. We then observe

INTRODUCTION: This lab was done to know how diffusion takes place. In the first place‚ particular penetrability is characterize as the particular "determination" with reference to what particles to enter the cell or kept outside of the cell; it is basically specific of what is going in and what is going out‚ primarily supplements going in and squanders going out (Marieb). Moreover‚ specific penetrability happens in two ways: dynamic process that requires ATP for the transportation of cell while

Lab #3: Mitosis and Meiosis To investigate the processes of mitosis and meiosis. Cells come from previous existing cells. New cells are formed by cell division‚ which involves karyokinesis and cytokinesis. Karyokinesis is the division of the cell’s nucleus and cytokinesis is the division of the cytoplasm. Mitosis and meiosis are the two types of nuclear division. Mitosis results in body cells: the formation of an adult organism from a fertilized egg‚ regeneration‚ asexual reproduction‚

Background: Techniques used were in accordance with NMU Professor Dr. D. Becker’s lab manual (ISBN 0-390-53911- 2; McGraw Hill). Changes in protocol or interpretation are noted where they were implemented‚ but strict adherence to the manual prevailed. Materials and Methods: Microscope‚ incubator‚ and deionizer functioned correctly throughout testing period‚ with stains‚ dishes‚ agars‚ and test reagents readily available. Lab procedures are considered orthodox and usage thereof is noted chronologically

Since the Grignard reagent can easily react with water‚ all glassware including the 25 ml round bottom flask‚ magnetic stir bar‚ 3 and 5 ml conical vial‚ 50 mL Erlenmeyer flask‚ claisen adapter‚ drying tube and 5 glass pasteur pipets were first added to a 250mL beaker and placed in the oven for 30 minutes. After the completion of the thirty minutes‚ 0.150 g of shiny magnesium turnings and a stir bar was first added to the round bottom flask and the claisen adapter along with the drying tube packed

Blood Smear Test – Haematology 21/11/12 Aim The aim of this experiment is to identify the morphological features of Erythrocytes‚ leukocytes and Thrombocytes‚ to carry out out a differential white cell count and to describe the parameters used to identify different types of anaemias. Introduction Blood is a specialised body fluid‚ which acts as a liquid connective tissue‚ by being involved around the heart and the blood vessels within the body. The main components of the blood is 55%

Introduction Using microscopes allows humans to see things they’ve otherwise would have never seen before‚ like cells. A cell is the basic unit of life. All living things are made of cells. All cells come from preexisting cells through a process called cellular division. There are two types of cells‚ eukaryotes and prokaryotes. Prokaryotes are very simple and small. They are unicellular and have no membrane bound organelles. Their DNA is found directly in the cytoplasm since they have no nucleus

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders
