experiment is to study how enzyme activity is affected by environmental conditions. Researchers tested the level of potato extract enzyme activity with 1-11 pH‚ varying temperature‚ catechol solution‚ hydroquinone solution‚ and different measurements of catechol. In Figure 1A and 1B‚ pH levels were tested with potato extract to see how pH would affect the amount of Benzoquinone is formed in the potato. Although it was hypothesized that enzymes would form Benzoquinone better in acidic pH levels‚ the absorbency

Controlled Assessment Task: State the hypothesis you will be testing in your investigation: The speed of a metal carbonate breaking down depends on where the metal is in the reactivity series. The more reactive a metal is the slower it takes for it to breakdown. The less reactive a metal is it breaks down faster. Explain the hypothesis using scientific ideas: The metal carbonate which is lower in the reactivity series such as copper can thermally decompose much faster because it is

Smoker pellets and wood chips are two of the most accessible and popular options for smoking food. They are two relatively modern twists on the use of smoke to preserve and flavor foods. In both cases‚ the basic principle remains the same—fire is applied to the fuel and smoke is produced; however‚ there are a couple of important differences between these two hardwood products. Let’s take a look at how they compare to each other. How do smoker pellets and wood chips differ? Both smoking pellets

How the Quantity of Money is Controlled The quantity of money available is called the money supply. In an economy that uses commodity money‚ the money supply is the quantity of that commodity. In an economy that uses fiat money‚ such as most economies today‚ the government controls the supply of money: legal restrictions give the government a monopoly on the printing of money. Just as the level of taxation and the level of government purchases are policy instruments of the government‚ so is the
