PRACTICAL 2 Title: Modelling of mitosis Objectives: To represent the pairs of homologous chromosomes by using pairs of model chromosomes. Introduction: Materials: 1. Noodles 2. Cutter Method: 1. The pair of model chromosomes is used to demonstrate how the two chromosomes line up at the beginning of mitosis. 2. After that the way of the sister chromatids of each chromosome separate into two separate chromosomes is demonstrated. 3. The spindle fibers that pull the sister chromatids apart is represented

people are at high risk to develop malaria‚ especially‚ with p. falciparum type of infection‚ pregnant woman‚ people with HIV‚ infants and children under the age of five years due to the decreased immunity in their body. P. vivax is one of plasmodium strains that have a dormant liver stage and it can activate and invade the blood after months or years‚ causing many patients to relapse. A malarial parasite that is exclusive to humans is P. malariae; this parasite can result in quartan fever and a chronic

Osmolarity TITTLE: practical of estimation of osmolarity in tissues by bathing samples in hypertonic and hypotonic solutions. INTRODUCTION: Osmolarity is the osmolar concentration of plasma and is proportional to the number of particles per liter of solutions shown as (mmol/l). It is derived from the measures Na+ and K+‚ urea and glucose concentrations. Since the volume of solution changes with the amount of solute added also it change in temperature and pressure‚ osmolarity we can say it’s

DNA Aim This practical procedure allows you to amplify a 460 basepair fragment of DNA from within the control region of the mitochondrial genome. This can be done using three water baths or‚ if one is available‚ a thermal cycler (PCR machine). After it has been amplified‚ the DNA is run on an electrophoresis gel. Note: This method has been adapted from one developed by the Dolan DNA Learning Center at Cold Spring Harbor Laboratory. More details are available from the DNA Learning Center’s

making each text more successful. The objective for both Austen and Weldon was to expose the impropriety of the social position of women‚ including myself‚ in the most accessible‚ interesting‚ and effective way possible‚ and hence Weldon deciding to write her text in epistolary form. A true representation of the inequity we as women encountered was made known through both Austen’s and Weldon’s texts‚ to intentionally create realisation and consequential change within society.

The Metamorphosis of the Practical Nurse October 23‚ 2006 The Metamorphosis of the Practical Nurse It takes a great deal of courage to let go of what is known‚ familiar‚ and comfortable. Change is a driving force in everyone. Like a butterfly‚ individuals in the nursing field may go through similar stages of metamorphosis‚ which is a process of growth‚ change‚ and development.

Method: 1) The materials for the practical were collected. 2) We set up a clean cutting area which consisted of placing newspaper onto the bench followed by the cutting tile on top. The liver was then cut into 1 cm cubes. 3) A 1 cm cube of liver was placed inside a 250mL measuring burette

Practical and Emotional Intelligence Practical and Emotional Intelligence Practical intelligence is an idea that has been considered by many psychologists over the years‚ yet only after rigorous examination and testing of the four criteria for a new intelligence can we declare if it is a new kind of intelligence. People seem to acknowledge a form of practical intelligence in their implicit theories of intelligence; "Street smarts" is a common conception separate from "Book smarts" to the average
