Sean Byrne Teacher Biology Honors 13 August 2014 Unit 1 Chapter 3 1) a. Monomers are small‚ simple molecules that when put together create carbon compounds‚ and polymers are molecules that consist of repeated units. b. Functional groups are made of clusters of atoms‚ while macromolecules are large polymers. c. A monosaccharide is a simple sugar‚ but a disaccharide is known as a double sugar‚ or two monosaccharaides. d. Long chains of amino acids are called polypeptides‚ and proteins are composed

What is Organic? The word ’Organic’ means ’living’‚ and in practical terms‚ this means natural food that is grown and processed without chemical fertilizers‚ pesticides‚ herbicides or fungicides. Nothing unnatural is allowed so there are no growth hormones‚ antibiotics‚ preservatives‚ dyes‚ chemical coatings or irradiation allowed. There is no genetic engineering allowed in organic foods. Organic food is nothing else but good pure nutritional food - the way it used to be. Toxic overload

AP Biology Dissolved Oxygen and Aquatic Primary Productivity Purpose: To measure and analyze the primary productivity of natural waters of laboratory cultures using screens to simulate the decrease of light with increasing depth. Background: Dissolved oxygen (DO) is how oxygen is measured. Oxygen is required in cellular respiration‚ so it is very important for aquatic life. When more oxygen is consumed than is produced‚ dissolved oxygen levels decline and some animals could die if they do not

Other nitrogen containing compounds Catecholamine: Dopamine‚ norepinephrine (noradrenaline) and epinephrine (adrenaline) are biologically active amines and are collectively called as Catecholamine. * Dopamine and norepinephrine functions as neurotransmitters. Outside the nervous system‚ norepinephrine and its methylated derivative‚ epinephrine regulates carbohydrate and lipid metabolism. They are released from storage vehicles in the adrenal medulla in response to stress (fright‚ exercise‚ cold

Modified Winkler Method for Dissolved Oxygen Determination Tiffany T. Lee Department of Biological Sciences‚ College of Science University of Santo Tomas‚ Manila‚ Philippines 1008 Date of Submission: February 17‚ 2011 Abstract In this experiment‚ the Winkler Method was used to measure the dissolved oxygen (d.o.) in a water sample from the pond in the Arch of the Centuries which had the owl statues. Then‚ the amount of oxygen is determined through a series of reaction. Usually‚ Winkler

EXPERIMENT 5- A FISCHER ESTERIFICATION SYNTHESIS OF PEAR OIL One of the major uses of Esterification (C(=O)-C-R) is forming compounds with different odors which can be used to make different synthetic and natural flavorings. Using the chemical and physical properties of organic compounds‚ an ester was catalyzed from the reaction of a carboxylic acid with an alcohol‚ producing an odor similar to that of pear oil. The mechanism of this Fischer- Esterification process is outlined as follows:
