Half-Life of M&Ms Introduction Half-life is the time required for something to fall to half its initial value. The half-life of a radioactive element is the time it takes for half of its atoms to decay into something else. M&Ms were chosen because they all have the same m mark on the on one side. In this lab you will go through predicting and counting the number of remaining "mark-side up" candies that should help understand that rates of decay of unstable nuclei and how it can be measured;

Abstract: We tested five common food items to determine which macromolecules were present. We tested for the macromolecules of simple and complex carbohydrates (sugars and starch)‚ lipids‚ and proteins. The foods tested were coconut milk‚ karo syrup‚ potato chips‚ peanut butter‚ and banana baby food. We hypothesized that coconut milk would contain all four types of macromolecules‚ karo syrup would only contain simple sugars which are monosaccharides and/or disaccharides‚ potato chips would contain

Introduction The objective of this experiment is to identify if the 12 provided solutions contain starch‚ glycogen‚ reducing sugars or proteins. The four major biological macromolecules are carbohydrates‚ lipids‚ proteins and nucleic acids. Abundant elements in the world such as carbon and nitrogen bond in different ways to form many different molecules. The functional groups are what determine their characteristics. During the experiment‚ there will be 3 test. The iodine test is completed to

With macromolecules‚ your body will be bigger‚ better‚ faster‚ stronger‚ and built to last longer! There are four major macromolecules that can give you more energy‚ strength‚ and enough fat to keep you warm and protected. In conclusion‚ the four major macromolecules are important to growth and development because they produce and store energy‚ create muscle to build a repair the body‚ create fat when it gets cold‚ and to tell when to release amino acid to build certain protein. Macromolecules are

Understanding the macromolecules in our bodies that are essential to our lives is what makes up molecular biology. One of the many things to understand about the macromolecules in our bodies is to first know about how they interact and types of interactions that are involved with each other‚ especially down to an atomic level. These interactions are included within types of covalent and non-covalent bonding. Covalent bonding involves the pairing of electrons that are shared between atoms‚ whereas

10.19.2011 TITLE: The Importance of Oxygen for Life PURPOSE: To determine whether test tubes filled with bacteria‚ a few salts‚ distilled water‚ and glucose would grow in the presence or absence of oxygen. By adding oxygen to certain tubes and withholding it from other tubes‚ one can determine which bacteria grow the most efficiently. HYPOTHESIS: The test tubes of bacteria with oxygen will grow and thrive over the test tubes without oxygen. METHODS: Using the data shown in Table 7-A-1

We have four important macromolecules; carbohydrates‚ lipids‚ proteins‚ and nucleic acids. From these four‚ the macromolecule I chose for this assignment was carbohydrate. Carbohydrates branch off into three main categories; monosaccharides‚ disaccharides‚ and polysaccharides. I decided to focus on disaccharides‚ specifically sucrose. Sucrose is more commonly known as table sugar. It has a chemical formula of C12H22O11. It is physically described as a white‚ odorless (although when heated‚ it may

In biology‚ there are four major biological macromolecules that are found in the cell‚ carbohydrates‚ lipids‚ nucleic acid‚ and proteins. Biological macromolecules are also known as organic molecules. Biological macromolecules are very large molecules that are of a key importance to living organisms. Most biological macromolecules are built by joining smaller molecule subunits. Carbohydrates are large groups of organic compounds found in foods such as sugars‚ starches‚ glucose‚ fructose‚ galactose

such. Although there are thousands of different types of molecules in a cell‚ only few are bimolecular like the four common macromolecules and many more. Proteins and carbohydrates are important factors of our food. To add onto‚ some simple molecules like vitamins and mineral salts also have a crucial part in the functions of organisms. The difficulty of even the simplest of life forms like the single cell‚ cannot and should not be exaggerated. If we were
