Tittle: Separation of leaves pigment. Introduction The photosynthetic pigment is used to absorb light during the process of photosynthesis. There are five pigments usually found in spinach leaves: Carotene (yellow)‚ Phaeophytin (yellow-grey)‚ Xanthophyll (yellow-brown)‚ Chlorophyll a (blue-green)‚ Chlorophyll b(green). Photosynthetic pigment is located in the chloroplast of the leaf. The function of chlorophyll a and chlorophyll b is to trap red and blue violet light when they carry out photosynthesis

Coal Seam Gas What is it? Coalbed methane‚ also more commonly known as coal seam gas (CSG) in Australia‚ is a type of natural gas removed from coal beds. It has been labelled as an unconventional natural gas along with tight gas and shale gas. They are labelled as "unconventional" as a result of their unusual reservoir types. It is removed from coal seams that are 300 - 1000 metres underground‚ and it is mainly composed of methane gas. It is typically extracted by drilling a steel-encased hole

Chromatography refers to a set of laboratory methods used in separating as well as purifying biomolecules. A variety of chromatography techniques exist‚ and all depend on the interaction between a stationary and a mobile state. Two types of chromatography methods were examined in this investigation. First‚ ion-exchange chromatography was used. This method separates ions and polar molecules based on their affinity to the ion exchanger [2]. Specifically‚ cation-exchange chromatography was performed

All children are unique and develop at their own rate but they tend to follow a similar pattern. There are a number of areas of development like‚ Physical‚ communication‚ Social‚ emotional‚ behavioural‚ Intellectual and moral development. Development is very rapid in the early years of a child’s life and tends to slow down the older they get. Moral development is usually adapted from the setting a child lives and would usually deem something wrong and right‚ based on what their parents believe is

Gas exchange or respiration in humans is the means by which getting oxygen from air into the blood and carbon dioxide out of the blood into the air. Humans must exchange these gases with the environment because oxygen is essential for cells‚ which use this vital substance to release the energy needed for cellular activities. In addition to supplying oxygen‚ carbon dioxide needs to be removed in order to prevent the buildup of this waste product in the body tissues. As breathing is the act or process

Experiment 3 Method of Flow Measurement Objective To demonstrate typical flow measurement devices for incompressible fluids: (1) venturi meter‚ (2) orifice plate and (3) rotameter. To compare the difference in flow rate incurred by each of these device. Overview In engineering and industrial practice‚ fluid measurement of many of the variables and properties‚ such as density‚ viscosity‚ pressure‚ velocity‚ flow rate and etc is one of the problems most frequently encountered by engineers
