This caused the production of oxygen (bubbles) to happen sooner and since both sides of the filter paper disks are reacting in the beginning (as compared to only one side reacting at the beginning until it somewhat rises into the 3% hydrogen peroxide solution) it resulted in a decrease in amount of time taken to rise to them top of 3% hydrogen peroxide solution which increases relative reaction rate of the enzyme catalase.The dried filter paper disks become less sticky and fall off the rubber stopper (when trying to insert them into culture tubes) into the 3% hydrogen peroxide solution before the culture tube was inverted.To fix this problem, heat up the catalase enzyme extract solution to the desired temperature condition and use that c...

Positioning choicesAt the beginning Brita company positioned the pitcher as a purification system providing water of unique taste.This functions as an asset to support and boost the sales of Brita’s pitcher (or any other water purification system), as there is high degree of brand awareness.Filters decrease health hazards by low quality tap water (even if not all dangers are eliminated).We believe that Clorox made an important decision for the promotion and advertising campaign under the idea of taste (“great tasting water”, “clear, fresh, wonderful”) because it was also consistent with the attributes of the core product (water indeed tasted better after filtration with a Brita pitcher).The publicity given to health problems due to water...
