In this file of SCI 207 Week 4 Laboratory Questions you will find the next information: 1. Identify natural and human-made causes of climate change visible in the computer simulation. According to the computer model‚ how have sources of heat-trapping pollution changed from 1750 to today? How does the simulation predict they will change by 2050? 2. According to the computer model and your readings‚ which source of heat-trapping pollution‚ contribute the most to climate change? Explain

The digestion process The digestion process begins in the mouth. First we take a bite of food. The presccence of food in the mouth stimulates the flow of saliva from the salivary glands. Saliva moistens the food and carries dissolved food molecules to the taste buds. Saliva helps digest food because it contains enzymes that start to break it down. After the food is covered with saliva‚ you then begin to chew your food. Chewing breaks down food into smaller pieces and also breaks apart fiber that

Cynthia Vang Derrick 24 Title: Digestion of Starch Problem: Hypothesis: If synthetic saliva breaks down the cracker the most Then more of the cracker should be digested Because synthetic saliva contains amylase‚ and amylase helps break down complex carbohydrates.

Living Digestion The first step in the journey of a sandwich is the mouth‚ where mastication occurs. The salivary glands secrete saliva which includes enzyme amylase. The teeth masticate and reduce the food into smaller pieces. The tongue moves the food around and enables swallowing. While the food is being broken into smaller pieces‚ amylase breaks down the carbohydrates found in the bread. After chewing (or mastication) is done‚ the food moves down the esophagus through peristalsis. The epiglottis

EXPERIMENT 13 DIGESTION IN THE SMALL INTESTINES ------------------------------------------------- ABSTRACT The small intestine serves as the site of major digestive and absorptive processes. In this experiment‚ the action of pancreatic enzymes on representative samples of each food group under different conditions‚ such as increased/decreased pH and presence of other substances‚ were observed. A pancreatin solution was first prepared from a hog pancreas and was completely neutralized using

Digestion and Enzymes – APP. Hypothesis: The enzyme‚ Amylase which is used to break down carbohydrates will work the best when heated at 40°C. Also‚ as the temperature increases the reaction rate of amylase increases too. However‚ the reaction rate of amylase will start decreasing when the temperature reaches the enzyme’s optimal temperature. Many enzymes are specific for a certain substrate. For example‚ lipase is a specific enzyme for fat substrates and protease‚ a specific enzyme for
