INVESTIGATE A FACTOR AFFECTING THE RATE OF PHOTOSYNTHESIS. Introduction Photosynthesis is a chemical reaction which takes place inside the green plants (plants with chlorophyll‚ a pigment found in chloroplasts which causes the colour of the plants and it is the main photosynthetic pigment) and light energy is converted into chemical energy. Carbon dioxide‚ water and sunlight is transformed into sugar an oxygen‚ which later will be used as energy for the plant. The chemical equation of photosynthesis

2.1 - Investigate why inquiries and serious case reviews are required and how sharing of findings affects practice Serious case reviews and inquiries are required to identify how‚ when and why a child has died from abuse or neglect. These reviews identify the way in which organisations and local professionals have worked both together and separately to safeguard‚ protect and promote the welfare of children and young people. These reviews also help to identify how these organisations could have

Investigate the effect of on exercise on the heart rate. Aim: To find out if there is any relevant link between the amounts of exercise taken to increase a person heart rate. Equipment needed: Stop watch Screen volunteer P.E kit Calculator Record sheet Type of exercise: skip for few minutes ‚ then break in between and again repeat it once or twice. Method: First of all‚ we needed to take the resting heart rate of the person who is about to skip. Then‚ with the stopwatch one

Another postulate of the kinetic molecular theory is that gas particles are always in motion‚ like the other states of matter. But they are different in that they undergo random translational movement. In solids‚ the particles mainly experience vibrational motion and in liquids they mainly vibrate and rotate‚ with some translational motion. Gas particles move rapidly in straight lines‚ unless acted upon by another particle or the walls of a container. This continuous contact with the container leads

Introduction The context of this paper is to investigate the relationship between capital structure and firm performance on Malaysia plantations industries. According to Brealey and Myers (1988)‚ the capital structure will determine the survival of a business. Damodaran (2001) defined capital structure as the mix of debt and equity used to finance the operation of firms. Capital structure is closed link with corporate performance (Tian and Zeitun‚ 2007). Corporate performance can be measured by

Experiment 3: Cryoscopic Determination of Molecular Weight Aim: The primary objective of the experiment is to calculate the total molecular mass of the compound benzoic acid in a predetermined amount of cyclohexane. Introduction: One of the key concepts in this experiment is the term freezing point depression. The definition of this phrase is that when a solute is dissolved into a solvent‚ their collective boiling point will be less than that of the original boiling point of the solvent. This incidentally
