Interpretation of Results As observed by the group in a normal diode circuit placed in a forward bias generates a sinusoidal output wave. In order to trim the output waves‚ that are a sinusoidal wave‚ to be generated‚ a clipper circuit was made with the use of diodes. The limiting level of a clipper circuit is the barrier potential of the diode in use. A diode clipper that trims down the positive half cycle input of a wave signal is as positive limiter. The output signal will retain the original

Macromolecule Report Monomer units of biological macromolecules have heads and tails. When they polymerize in a head-to-tail fashion‚ the resulting polymers also have heads and tails. These macromolecules are polar because they are formed by head to tail condensation of polar monomers. Making Glucose: Green plants manufacture glucose through a process that requires light‚ known as photosynthesis. This process takes place in the leaf chloroplasts. Carbon dioxide and water molecules enter a sequence

A macromolecule can best be described as an immense molecule‚ made up of thousands of covalently bonded carbon atoms. There are four classifications of macromolecules: carbohydrates‚ lipids‚ proteins‚ and nucleic acids. Each classification performs specific functions that allow cells to grow and survive. Macromolecules can be either split or bonded through dehydration synthesis or hydrolysis. Dehydration synthesis occurs when water is released‚ electrons become shared‚ covalently bonding two

Half Life Experiment My hypothesis would be that after each shaking about half of the remaining candies would be logo-up and half of them logo-down. That’s why the shaking represents a "half-life". half-life || total time (sec) || # of undecayed atoms || # of decayed atoms 0 0 100 0 1 5 65 35 2 10 51

IDENTIFICATION OF SOME MACROMOLECULES | | INTRODUCTION Dehydration-synthesis is a reaction that occurs to form different types of macromolecules. It is a reaction that leaves a macromolecule structure along the lines of developing its own specific function in a living organism. The 4 most common ones are carbohydrates which includes monosaccharides and polysaccharides‚ lipids‚ proteins and nucleic acids (Mack 2012). Scientists identify different types of macromolecules to achieve a better

Test for the Presence of Macromolecules Introduction In this experiment‚ we are trying to identify the presence of macromolecules in certain solutions. As in our daily lives‚ macromolecules are the essential nutrients that we have to take every day‚ therefore we would like to identify the types of macromolecules that contain in some of the food or solution in order to maintain a healthy life. There are four groups of macromolecules which are carbohydrates‚ lipids‚ proteins and

Macromolecules BCM261/BCM262 Anonymous Student #2 Aim The purpose of this lab was to use the scientific method to identify an unknown solution‚ based on the reactions (i.e. color changes) of known solutions with indicator solutions. These known solutions contained different types of macromolecules. Each type of micromolecule reacted with at least one indicator solution in a unique way‚ which allowed us to identify the macromolecule based upon the presence or

In the sandwich you just ate‚ you have consumed three raw macromolecules. The bread would be considered the carbohydrate. The mayonnaise is the lipid. The turkey is of course considered the protein. Although the body takes in these three different forms one way‚ the way the body breaks it down is in three ways. First is the break-down of the carbohydrates(bread). The polysaccharide form of this is too big for the body to simply break down directly. So‚ instead the body uses multiple forms of procedures
