affecting the rate of catalase activity The extent at which environmental factors affect the rate of catalase activity was discovered in this lab. The assay system‚ in which a filter paper disc was dipped into the enzyme and submerged using a stirring rod in a test tube filled with 20mL of hydrogen peroxide‚ was used to test several enzyme factors. As the saturation of hydrogen peroxide increased the rate of reaction increased as well. When the enzyme concentration increased the rate of catalase activity

When our eyes are exposed to a hue for a prolonged period‚ the rods & cones become fatigued. You might notice this if you are reading something on colored paper‚ and then look away—you often see the inverse‚ or complement‚ of the image. This occurrence can be advantageous if you are seeking the opposite‚ or contrast

Benjamin Franklin was born January 17‚ 1706 in Boston‚ Massachusetts. He is known for inventing things such as the bifocals‚ the Franklin Stove‚ the glass harmonica‚ and the lightning rod. In 1732‚ he published Poor Richard’s Almanac. Ben also helped write and review the Declaration of Independence. He helped work out the Treaty of Paris‚ which ended the Revolutionary war. In 1746‚ Ben found work from other scientists on their electrical experiments. While he was doing an experiment‚ he shocked himself

Amanda Lab Report 1 Microbiology Laboratory Title – Differentiating Organisms using the Gram Stain Introduction The experiment conducted was based upon the known attributes of two different groups of bacteria‚ those that are gram positive‚ and those that are gram negative. Using a specific staining procedure‚ it is possible to differentiate the two types under a microscope The gram stain method of differentiation is possible because of differences in the cell membrane between the two categories

Q.1. What is the distribution of rods and cones on the retina? What results did we observe from the visual field experiment that confirms this? In your response describe the data collected and correlate the data with the known distribution of rods and cones.(10 points) Rods are very sensitive and respond to very dim light making them best suited for night and peripheral vision. Cones need bright light for activation because they have a low sensitivity but react more rapidly. Cones furnish vivid

atoms‚ however‚ are very unstable and release large quantities of energy. This atomic energy is utilized within a nuclear reactor. Uranium‚ a radioactive element‚ is the fuel of most nuclear reactors. Uranium rods are allowed to interact with each other in the core of the reactor. As the rods interact‚ the radioactive uranium atoms decay and release great amounts of heat. The heat is used to change water into steam. The steam is forced through pipes until it reaches giant turbines. The steam pressure

On March 11‚ a 9.0 magnitude earthquake hit Japan and caused tremendous damage to Japan. The earthquake sparked off a 30-foot tsunami within an hour‚ which only compounded the‚ already extensive‚ damage to the country. One of the greatest fears was the potential of a nuclear fall out. Specifically‚ the Fukushima Daiichi power plant was in question. The nuclear plant in Fukushima had six nuclear reactors‚ and three out of six of them were in critical state – possibly melting down. The potential of

The ‘rods’ are thin‚ cylindrical receptor cells in the retina that are highly sensitive to light‚ they also play a role in peripheral vision. Since the pilots sat in the dark cock-pit the rods in their eyes were more sensitive to the light they saw. 3) What cues might Captain Mueller

length of the handle to its cooler free end. This is because one end of the rod is held at the high temperature‚ and the other end stays at the lower temperature. Although the rod itself doesn’t move‚ heat flows down it like a current because points along the rod have different temperatures. Just as a change in voltage produces a current in an electrical circuit‚ the change in temperature causes heat to be conducted along the rod. • Convection. In addition to conduction‚ heat can also be transferred
