Answer:
Option D: More than 30 seconds
Explanation:
The enzyme CATALASE is found in almost all living organisms. CATALASE helps in the decomposition of one substance into another substance. CATALASE will breaks down hydrogen peroxide into water and oxygen.
When the potatoes were boiled it will surely produce no bubbles because the heat would have degrade the enzyme - catalase While the potatoes at room temperature potato produced the most bubbles because catalase works best at a room temperature.
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 MORE THAN 30 SECONDS
That's because the solubility
- Temperature is directly proportional to solubility
Higher the solubility higher the temperature
Lower the temperature lower the solubility
So
Less temperature makes enzymes work faster
Answer:
B.
Explanation:
The telescopes of the 1600s were gradually improved upon over time, resulting in the telescopes that are available today.
