One way to show the presence of CO2 is to test lime water and see if it goes milky. A detailed description of the experiment is in related links.

If you have just performed an activity using plant seeds Prepare a system where you test respiration in a small animal In the space provided below draw what that system would look like?

To test respiration in a small animal, you would need a closed chamber with a sensor to measure oxygen consumption and carbon dioxide production. The small animal would be placed inside the chamber, and the changes in gas levels would indicate the rate of respiration. This setup would allow you to quantify the animal's metabolic activity through respiration measurements.


What role was played by the glass beads in the cellular respiration experiment?

Glass beads were used in the cellular respiration experiment as a control to ensure that any changes observed were due to the presence of living organisms (yeast) and not simply the physical presence of an object in the test tube. The glass beads did not respire, so any changes in gas production or respiration rate observed in the experimental group could be attributed to the yeast cells metabolizing the sugar.


What indicates a test for catalase production is positive?

A positive catalase test result is indicated by the presence of bubbles or effervescence when hydrogen peroxide is added to the test organism. This indicates the production of the enzyme catalase, which breaks down hydrogen peroxide into water and oxygen gas.


Does Sarcina test positive or negative for the voges-proskauer test?

Sarcina typically tests negative for the Voges-Proskauer test. This test is used to detect the production of acetoin, and Sarcina species do not produce significant amounts of this compound.


How do you make ignition test of organic compound?

The Ignition test is a test for aromaticity. One takes a sample of their unknown, places it in an open flame and observes what happens. The presence of an aromatic ring will usually lead to the production of a sooty yellow flame in the test.
