LAB 1 1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points) a. Eye Wash (2 points) The eyewash fountain is used to rinse chemical splashes off the eyes. They are used by rinsing the eyes 15 to 30 minutes with water. b. Fire Blanket (2 points) Fire blankets are used to extinguish small fires. They are used by covering the small fires with the blankets until it extinguishes. c. Shower (2 points) Safety showers were made to eliminate any

Throughout this lab‚ diffusion and osmosis has been seen and tested through experiment. In part A of the lab‚ diffusion was demonstrated with two solids and an agar gel petri dish. One crystal of potassium permanganate and one crystal of methylene blue were placed on either side of an agar gel petri dish. The purpose of this experiment was to determine which of the crystals would diffuse across the gel more. So the question is‚ which solid would have a higher rate of diffusion through the agar‚ methylene

The experimental samples for the pH concentration experiment were put together by using a 10ml-graduated cylinder to obtain 4ml of each pH buffer to insert into cuvettes‚ a micropipette was then used to obtain 0.5ml of catechol and 0.5ml of the catechol oxidase. The pH buffer was made first to avoid any denaturation of the catechol oxidase. Our positive control for this experiment was pH 7 because that is the pH level of most cell membranes in the cytoplasm (Whitson‚ 2016.) Our negative controls

Voyager 1 and 2 were originally a spin off of the Mariner program‚ originally called Mariner 11 and 12 but they decided to change the name. Voyager 1 and 2 were to look at our solar systems gas giants. They both were using a new technique called gravity assist to help maneuver. Voyager 1 and 2 are powered by radioisotope thermoelectric generators (RTG). The mission plan for Voyager 1 and 2 was to look at all the gas giants in the solar system they called this plan the grand tour‚ the planets include

Rate of Osmosis vs Solute Concentration Introduction: In nature‚ the quest to reach equilibrium‚ or the state of rest or balance due to the equal action of opposing forces (http://www.dictionary.com). Osmosis and diffusion are two ways that cells reach this equilibrium‚ without exerting energy. Due to the unique nature of the phospholipid bilayer‚ small molecules can pass through the semipermeable membrane easily‚ through diffusion (https://www.biologycorner.com). Water‚ however‚ has a slightly more
