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.
Answer:
igneous rocks
Explanation:
igneous rocks forms from lava, such as obsidian, basalt, plumice, etc
Each particle has two possibilities: either it is on the left hand side or it is on the right hand side.
The probability of having them equally split is
P(100,100) = 200C100 / 2^200
where 200C100 is the binomial coefficient.
For the uneven distribution we have
P= 2 * 200C160 / 2^200
where the factor 2 comes in because we could have 160/40 or 40/160 as a division.
So the ratio of probabilities is
200C100 /(2 * 200C160 )
= 2.2 * 10^16
Hope this helps!
