The Cause of the Mass Extinction in the Late Cretaceous Period Dinosaurs first appeared around 245 million years ago‚ and they lived for 180 million years. Then suddenly‚ 65 million years ago they went extinct. Not only did all the dinosaurs die out‚ but also up "to 75% of all marine genera were lost" ("mass extinction"). This leaves scientists wondering about what could have led to this mass extinction in the Cretaceous Period. They have collected evidence from fossils and earth’s geography‚ to

DIGESTION OF CARBOHYDRATES Digestion of carbohydrate begins in the mouth‚ with the secretion of the enzyme salivary amylase from the serous cells of the salivary gland. This enzyme breaks starch and glycogen into disaccharides. The mucous cells of the salivary gland secrete a mucus‚ which causes the food to stick together‚ and acts as a lubricant to aid in swallowing. The salivary glands are grouped into three categories: the parotid gland‚ submandibular glands‚ and sublingual‚ all located

Remember that we live in a parasitic world and that everyone is infected. No longer people are people. They claim to be temples and what is in them the parasites claim to be whatever they came from.
