Participant Obvservation Sociology is the systematic study of humans in groups. There are different ways to study these groups of humans and most sociologists are aware of the different ways. As a student studying sociology the class was given a task to observe human interactions in groups and relate what I found out to what I have learned so far. Out of the many different ways to study groups we had to use participant observation‚ systematically studying people while joining them in activities

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

proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing with the four organic molecules are proteins. Proteins provide structure and function and have the chemical structures of Carbon‚ Hydrogen‚ Oxygen and Nitrogen.

BIOL 130 Lab Report Identifying Two Macromolecules - Carbohydrates and Proteins 9/26/2013 [Type the company name] INTRODUCTION As the name suggests‚ macromolecules are large molecules that make up more than 90% of the total cell mass. These biological macromolecules vary greatly in size - from several hundred to several hundred million molecular weight units - and are made up of monomer units. There are four major classes of biological macromolecules: proteins‚ carbohydrates‚ lipids

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

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

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

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

The results of the lab seemed mostly reasonable. The only result that didn’t seem right was the cheese. Cheese is a dairy product which contains proteins however‚ the Big Macs cheese didn’t have proteins. Other than that the lab results looked right. The food product would match up with the correct macromolecule.
