Chapter Four DEFINITIONS nucleic acid – polymers specialized for the storage‚ transmission between generations‚ and use of genetic information. There are two types‚ DNA and RNA nucleotides – monomers that compose nucleic acid‚ consist of a pentose sugar‚ a phosphate group‚ and a nitrogen containing base. DNA - – a macromolecule that encodes hereditary information and passes if from generation to generation. RNA and the bonds that stabilize them Purine - one of two chemical forms

Introduction: The purpose of this lab was to take a variety of solutions and test their pH. Due to materials available pH strips were the only testing tools available. A table is setup to compare the strip color to its pH level. Four known solutions including bleach‚ lemon juice‚ soda‚ and baking soda were used. There was also an unknown solution in which the pH level was used to determine which solution it was. The pH scale is 1-14‚ a pH of 7 is neutral‚ less than 7 is acidic‚ and greater than

In this investigation‚ me and my partners performed an experiment to find the different energy contents in food and different amounts of energy released when consumed. Throughout this experiment our procedure was to take different food samples and use a device known as a calorimeter made from a can of aluminum‚ one large paper clips and a string of copper wire to measure the amount of thermal energy released during a reaction. By measuring the temperature difference before and after a reaction‚ the

USES OF LILIACEAE Lilies are highly prized as house and garden ornamentals‚ and many of the most beautiful of these belong to the genus Lilium‚ the namesake of the family Many lilies have enchanting fragrances that are sometimes extracted for use in perfumes. There was a hysterical rush to raise and breed new and rarer varieties of tulips. Speculators invested

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

sterilization process. Where does it come from? Nonradioactive cobalt occurs naturally in various minerals and has long been used as a blue coloring agent for ceramic and glass. Radioactive Co-60 is produced commercially through linear acceleration for use in medicine and industry. Co-60 also is a byproduct of nuclear reactor operations‚ when metal structures‚ such as steel rods‚ are exposed to neutron radiation. What form is it in? Co-60 occurs as a solid material and might appear as small metal disks

However‚ if red blood cells are placed in a hypotonic solution‚ or one with a lower solute concentration than in the cells themselves‚ this can be highly detrimental. The purpose of this lab is to
