series of biochemical tests was carried out to identify unknown carbohydrates. There were six carbohydrates that needed to be identified; they have been randomly labelled A-F. The carbohydrates are glucose‚ fructose‚ maltose‚ lactose‚ sucrose and starch. There was six tests that were carried out to help identify them‚ these were: Iodine Test‚ Solubility in Water‚ Benedict’s test‚ Acid Hydrolysis‚ Barfoed test and Diastix test. Aim The aim of the experiment which was carried out was to identify

use ‚ is the Bioplastic which is one of many remedies scientists are really looking forward for and relying on. Bioplastics are plastics derived from renewable biomass sources‚ such as vegetable fats and oils‚ corn starch‚ pea starch or microbiota. Bioplastic types such as starch-based plastics or PHA are potentially biodegradable. This feature is directly linked to the chemical structure of the polymer and can benefit particular applications. Biodegradable plastic types offer new ways of recovery

Food and Nutrition Assignment Submitted by: Azka Khan Submitted to: Topic: Types of Food Types of Food Food: Food is any substance normally eaten or drunk by living things. The term food also includes liquid drinks. Food is the main source of energy and of nutrition for animals‚ and is usually of animal or plant origin. There are 4 (four) basic food energy sources: fats‚ proteins‚ carbohydrates and alcohol. Historical development Humans are omnivorous

IDLY SCIENCE REASONS FOR IDLY AND DOSAI MAAVU NOT GETTING PROPERLY FERMENTED 1) Both batters need Bio activity. So if there is not enough bacteria/Fungus/Yeast present in the batter‚ the maavu will not ferment or will not ferment properly. 2) If you are using chlorinated‚ Iodised water or bacteria free water or Ozonized water in your house‚ you will not be able to get proper fermentation in batter as all these chemicals have residual disinfection property.(except Ozone) . 3) If

and forth. A propelling movement is one where the muscle contraction occurs in the wall of the tube but the muscles just ahead in the tube relax. 5. Discuss the functions of the mouth and its parts. The mouth receives food and prepares it for digestion by mechanically breaking up the size of solid particles and mixing them with saliva. The cheeks are the outer layers of skin‚ pads of subcutaneous fat‚ and the muscles associated with expression and chewing. The lips are highly mobile structures

3. List 4 abdominal organs that you observed. Describe their position relative to each other using correct anatomical terms. (Rachel Mindel) The pancreas is located in the upper abdomen‚ is posterior to the stomach and some parts are in between both the stomach and the spine. The right side of the organ which is called the head‚ is nestled in the curve of the duodenum (juncture where the stomach meets the first part of the small intestine). The tapered left side of the organ is called the body

Kowal] In this essay‚ the use of plastic made from polylactic acid or PLA (a kind of starch-based polymer) will mainly be discussed‚ because they are one of the most commonly used and cheapest-costing of all biodegradable plastics. PLA is made from the starch in corn (or sometimes wheat) plants‚
