Cystic Fibrosis
Cystic Fibrosis Cystic fibrosis is an autosomal recessive trait on chromosome 7. This disorder affects chloride transport resulting in abnormal mucus production. This lifelong illness usually gets more severe with age and can affect both males and females. Symptoms and severity differ from person to person. Cystic fibrosis is the most common fatal inherited disease among whites and the major cause of chronic lung disease in children. 50% of people are expected to live to be 30, but a majority di

Diverrsity of Plants
Diverrsity of Plants Plants evolved more than 430 million years ago from multicellular green algae. By 300 million years ago, trees had evolved and formed forests, within which the diversification of vertebrates, insects, and fungi occurred. Roughly 266,000 species of plants are now living. The two major groups of plants are the bryophytes and the vascular plants; the latter group consists of nine divisions that have living members. Bryophytes and ferns require free water so that sperm can swim

How Nutrients Get in, and Wastes Out.
How Nutrients Get in, and Wastes Out. By Faisal Premji Science 10 Assignment -- Part B In a human being, nutrients are necessary for survival. But how are these nutrients obtained? This report will go into depth on how the food we eat gets into our cells, and how the waste products that we produce get out of the body. Also, the unicellular organism Paramecium will be compared with a human being, in terms of all of the above factors. Dietary Nutrients The chief nutrients in a diet are classified

Lab Report for Lab 6 Biology 101 October 16, 2003 Introduction Background Information: Enzymes are proteins which act as catalysts which speed up the chemical reactions. Substrates are the reactants that yield products by the means of enzymes. As long as the temperature pH and concentration are held together or in right amounts, enzymatic activity will carry on by giving off energy as heat. Extereme pHs [Low(acidic) and high(basic)], high temperature, and high concentration will denature the enz

Digestive System Notes
Digestive System Notes the digestive tract:-begins with the oral cavity and includes the pharynx, esophagus stomach, small intestine, large intestine and anus. Be able to label the parts in the diagram below Oral cavity- teeth tear and grind food and the tongue mixes food with saliva. Functions of saliva i. It contains an enzyme (salivary amylase) that breaks down starch to maltose ii. It moistens the food and forms a food ball iii. It lubricates the esophagus so swallowing in made easier Pharyn

Design an investigation to test the effect of temp
Design an investigation to test the effect of temperature on the rate of reaction of amylase Prediction I predict that increasing the temperature will increase the rate of reaction up till 40c. After that the rate will begin to decrease and stop as the enzyme becomes denatured. Method See coursework I will repeat the experiment 5 times at each concentration and take an average of the results

Following the progress of an enzyme-controlled rea
Following the progress of an enzyme-controlled reaction. Aim: To follow the progress of an enzyme-controlled reaction using starch solution and amylase. Hypothesis: It may be assumed that the longer the starch will be in contact with the enzyme the more starch will be converted into maltose. It can also be expected that the more substrate is digested into the break down product the lower color readings will be obtained with the colorimeter confirming the hypothesis that as time goes by the amyla

The Digestive System
The Digestive System The digestive system is responsible for processing food, breaking it down into proteins, carbohydrates, minerals, fats, and other substances, and inject them into the bloodstream so that they can be used by the body. The digestive, or alimentary, tract begins at the mouth, where the teeth and tongue begin the breakdown of food, assisted by saliva from the salivary glands. Saliva contains enzymes which break up food and cause other chemicals to react easily with it. Two of th

The Digestive System
The Digestive System Digestion is a process in which your body converts your food into simpler forms which can be used to supply energy and building materials for growth. Food enters your body through your mouth. Your tongue moves the food around while your teeth chew it up. The tongue also aids in the process of swallowing the food. The salivary glands add saliva to the mouth. The saliva contains an enzyme call Salivary Amylase which changes the starches in the food to sugars. These sugars give

Digestive Systems
Digestive Systems The digestive systems works on nutrients taken from the environment, breaking them down into simpler products, and then absorbing the products together with water and salts so they can be used in metabolism. The individuals of all species contain many different protiens or carbohydrates in the cell walls of bacteria, chitin in the external skeletons of arthropods, and so on and foreign proteins or carbohydrates are rarely incorporated unchanged. They are usually first broken do
