Biology Form Four Digestion Digestion is the process by which food is broken down from complex insoluble substances into simple soluble substances. There are two types of digestion – chemical digestion and mechanical digestion. Mechanical digestion involves breaking up large pieces of food into smaller pieces. This provides a large surface area for the action of enzymes on food. There is no change to the chemical composition of food during mechanical digestion. Mechanical digestion occurs in

It has been hypothesized that the index patient becomes infected through contact with an ill animal. After the first case patient‚ the virus can be transmitted through direct contact with infected blood or secretions or through contact with contaminated objects such as needles.

Outline of species along with related anatomy‚ handling considerations and rehabilitation‚ release requirements Skeletal system Although the deer’s skeletal system is very similar to a dog or cat’s in terms of its basic structure‚ although there are some adaptations that they require in order to survive the wild. Deer have long necks which enable them to crane it so they can feed off low lying grass and other vegetation. Stefoff‚ R. (2007) Deer are prey animals and so they require adaptations
