system. The tongue‚ teeth‚ hard palate and soft palate helps to mix and to reduce size of food put into the mouth. The parotid glands‚ the sublingual and the submaxillary grans secret saliva to help the process of chewing food. Saliva contain salivary amylase enzyme responsible for breaking down sugars and starches. The epiglottis prevents food from entering the larynx-at the upper-part of the respiratory system. The tongue helps also to swallow the food.

The effectiveness of lemongrass essential oil incorporated into starch based bio-coating in lengthening the shelf life of Carica papaya (Papaya) was tested through the application of different concentrations of lemongrass essential oil and starch treatment on the papayas. The Peel Color Index (PCI) of each papaya was determined 4 days after the application of starch bio-coating. Table 1: Mean Peel Color Index of Carica papaya for Day 0 and Day 4.

The body is made up of a number of systems that all interlink and produce everything we need in order to survive. Within the body there is the digestive system; the circulatory system‚ the nervous system‚ the muscular system‚ the skeletal system and the reproductive system. These systems are all part of one another and they share organs‚ tissues and cells and that is how they interlink. The diagram above shows each system and where they are located in the body. Each system is shown in a different

Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide

[1]The method consists in a solution of neutral detergent which melt from solid to liquid pectins and plant cell components‚ such as proteins and lipids.[2] The solution is applied to solubilize proteins. The addiction of the amylase enzyme‚ which occurs twice‚ is made in due to broke starch bonds and aid in the analysis. The main disadvantage of this method is that the soluble fibre cannot be measured [1]. 2. Results To calculate the percentage dietary fibre the following

Reproduction Fact Sheet Male: Sperm Female: Ovum (egg) What happens to Gametes at Fertilisation? Fertilisation is the process where sperm (from the male) and the ovum (from the female) fuse together to form the zygote. Each gamete contains 23 chromosomes which combine together‚ in the zygote‚ to combine to a full set of 46 chromosomes – half from the father and half from the mother.. Summed up‚ it is where the male gamete and a female gamete join. The fusion of gametes enables the genetic
