cellular respiration to produce ATP. This process takes place in chloroplasts‚ which is a plastid that contains chlorophyll and involves two interlinked reactions‚ which are light dependent reactions and light independent reactions. Throughout our lab experiment‚ we focused on the affect access of light has on carbon dioxide during photosynthesis. Carbon dioxide levels decrease as oxygen levels increase and glucose is produced when light dependent reactions occur. Light energy is absorbed by photo

G. Y. S. Period: 6 09/11/12 Osmosis Lab I. Objective: The purpose of this lab is to put the solutions in chronological order from least to most molarity. If the solutions are hypertonic then‚ the water will go in and the order of the substances will be C‚ D‚ A‚ B‚ E. II. Materials and Methods: See attached page. Results: Table 1.1 III. Table 1.1 | Initial | Final | % Change | A | 11.4 | 11.86 | 4.03% | B | 11.67 | 15.33 | 33.68% | C | 10.84 | 11.86 | 9.4% | D | 12.02 |

Unlike most coefficients in Physics‚ friction behaves differently depending on whether the object is at rest or at motion.

grow onions Today‚ most people simply eat onions raw or cooked‚ in about a thousand different ways. Onions are warm-season veggies and‚ however you plan to use them‚ you can grow them anywhere following the following easy steps: a) Buy started plants at the nursery. Otherwise‚ start seeds indoors 8 to 10 weeks before the last expected frost (see "How to Start Vegetable Seeds Indoors"). b) Choose a site that gets at least 6 hours of sun a day and has soil with a pH of 6.0 to 7.5. Onions need moderately

(Staudt 80). In this lab‚ solubility in water‚ acidity‚ and odors of carboxylic acids will be observed. Also‚ esters will be produce and odors will be detected from the product. Finally‚ saponification will be learned. PROCEDURE: Carboxylic Acids and Their Salts: Characteristics of acetic acid: 2mL of water and 10 drops of glacial acetic acid was placed into a clean‚ dry test tube. Before

Diffusion and osmosis go hand-in-hand. Osmosis is generally the same as diffusion‚ however‚ deals solely with water. Osmotic pressure is the pressure of a solution against a semi-permeable membrane to prevent water from flowing into the membrane. In this lab‚ we are going to study tonicity; tonicity is the measure of this osmotic pressure and is the differential of pressure between two solutions separated by a selective membrane. To help identify the relative concentrations of solute particles of different
