Introduction The cane toad is regarded as one of Australia’s most highly invasive and feral species. Native to central and south America‚ 3000 were released in 1935‚ onto sugar cane plantations. This occurred in hopes of devouring cane beetles that caused a lot of damage to the crops.

Protein in the Digestive System Taylor Adams Biol 112- 501 18 April 2016 Introduction Proteins are found in nearly all foods that we eat.

Yet alcohol inhibits the brain’s ability to send signals to the spinal cord and nerve endings. The nervous system slows down greatly because it is absorbed right into the blood stream. Alcohol works the same as a sedative without the benefit of going through your digestive system. Because it enters directly into your blood stream‚ it is very dangerous. Your

The monogastric digestive tract is quite similar to the ruminant digestive tract‚ in the way they have many of the same parts and they process the food similarly. The mouth‚ oesophagus‚ liver‚ pancreas‚ gall bladder‚ small intestine‚ and large intestine in a ruminant species have similar functions to monogastric species. Both the digestive tracts start with the mouth‚ and although they are formed differently in order to eat the different diets‚ both the mouths are used to grab‚ chew and push the
