Subject: Study Skills
Please describe the ideal study setting.
In theory the ideal study setting is a sturdy, high backed chair, at a desk with no background noise and only your study materials in front of you with bright lighting. However, it can be argued that everyone studies differently and each person may have their own ideal study setting. Classical music, a more comfortable chair, or even a walking desk might be applicable for your own unique situation.
Subject: Environmental Science
What is the difference between biotic and abiotic?
Biotic organisms are the living parts of the environment such as plants and animals and bacteria and the abiotic parts of the environment are the non-living parts such as the rocks.
In your own words describe the digestion process.
Food enters through your mouth where physical break down begins to occur. Your teeth begin to chew the food to increase the surface area and saliva mixes with the food to create a paste. This is also where enzymes that break down carbohydrates are introduced called amylase. The food then is swallowed and moved to your esophagus where peristalsis begins to move it towards your stomach. Once it reaches your stomach, stomach acid mixes with the food to create a substance called chyme. The stomach is also where enzymes that break down protein is introduced. Once the food is turned into chyme it enters the small intestine. Once in the small intestine bile created by the liver and stored in the gall bladder along with pancreatic juice are added to the mixture. Bile has enzymes to break down fat and the pancreatic juice has enzymes which break down starches, fats and proteins. Peristalsis continues in the small intestine pushing food now known as chyme along. The small intestine is also where nutrient absorption happens. The liquid then passes into the large intestine. By this point most nutrients should have been removed. In the large intestine water is removed and absorbed by your body. The remaining products are now waste and are stored in the rectum until your body excretes them.
