If the potato solution was boiled for 10 minutes and cooled for 10 minutes before being tested, the average time for the disks to float to the surface of the hydrogen peroxide solution would be:.A) 5 secondsB) 10 secondsC) 30 secondsD) more than 30 seconds

 The correct answer is :  D) more than 30 seconds

Explanation:  This experiment is carried out in order to study the actions of the catalase enzyme on hydrogen peroxide. Catalase is extracted from potatoes and stored on ice. 1%, 5%, 10% and 15% hydrogen peroxide solutions are prepared. Filter papers are soaked with the catalase and then placed inside each hydrogen peroxide solution. Then the time it takes for the filter paper discs to float from the bubbles that are produced is measured.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
