(Science Buddies on March 8‚ 2012) Aim : The objective of these experiments is to investigate the change in the decomposition rate between the catalase and hydro peroxide with cooked and raw potato and liver. Hypothesis: With consideration to previous studies done into the topic. It is hypothesized that the raw food will provide a higher rate of reaction than the cooked food will as the cooked food would have a higher chance of having denatured

In the potato chip industry in the Northwest‚ moving from a monopolistically competitive market place to a monopoly has different ramifications for the potato chip manufacturer and the various stakeholders.

This is done by adding a drop of IKI reagent to the potato and the onion and examining both of them under a microscope looking for cell presence. I think that there is more starch in a potato than an onion. The potato under the microscope (160m magnification) without IKI reagent

What is special about this data set is that it comprises three particular ‘salty snack’ product types – potato crisps or chips; corn chips; and extruded snacks that take the form of rings or shapes. Therefore the data provides the opportunity to apply the Duplication of Purchase law to brand-level competition but also to examine the broader competitive level
