proteins, carbohydrates, and lipids, which are composed of smaller molecules known as monomers and polymers. Polymers are joined monomers. A chemical reaction links monomers together occurs and releases a water molecule, this is called dehydration synthesis. Hydrolysis separates polymers into monomers by using water to break bonds. Organic catalysts called enzymes are proteins that increase the speed of a chemical reaction. In the lab we used Biuret reagent to test for proteins, iodine solution to

IncorrectQuestion 1 0 / 1 pts Which of these is an example of homeostasis? Hummingbirds prefer to feed on nectar from red flowers. Homeostasis is the maintenance of the body's internal state within a relatively narrow range. When the dog's body temperature becomes too high, the animal feels hot. He opens his mouth, lets his tongue loll out, and pants until he feels comfortable again. A shark can detect even minute quantities of blood in the water. Venomous coral snakes and harmless

of these macromolecules are formed from functional groups. The functional group hydroxyl is found in every macromolecule. All of these macromolecules except for lipids are hydrophilic. All of these macromolecules are broken down into monomers by hydrolysis reactions. Proteins have methyl groups, amino groups, and carboxyl groups. Proteins are polymers of amino acids. Proteins functions are determined by how they are folded. Proteins with a primary structure have no function. Proteins with a secondary

specific heat 7. Heat bank 8. Heat of vaporization allows evaporation cooling. 9. Abundant and versatile solvent 10. Solid is less dense than liquid 11. It is a reactant and a product in many biological reactions (Photosynthesis, dehydration reaction, hydrolysis…) 12. It can ionize into H3O+ and OH- • When substances dissolve in water, water molecules form hydration shells by breaking their attractions to other water molecules and attracting to the solvate particles. • The dissociation of

limited to books. If you delve a little you will get to know these reactions happen in our common day to day life or it may be a part of the processes living organisms undergoes. Similarly, nucleophilic addition reaction helps in the biological synthesis of compounds in metabolic processes of living organisms. The reactions also form part of the pharmaceutical preparation processes in industries and academia. The reaction helps in the formation of new complex organic chemicals. Therefore, nucleophilic
