Imagine you are working in a real lab setting and when you test the catalase and water together you see a reaction. What does this tell you?(select all that apply) - catalase is not specific to hydrogen peroxide -posible contaminant in the water causing a reaction -catalase is the negative control -you must complete the experiment again to verify your results

If you are working in a real lab setting and you found out that testing the catalase using water produced a reaction, it is highly likely that the water is contaminated.

Catalase is an enzyme that is substrate specific and its substrate is hydrogen peroxide. The enzyme breaks down hydrogen peroxide to produce water and oxygen. The latter is often seen as bubbles in reactions and the equation is as follows:

Ordinarily, catalase will not produce any reaction with water. However, if the water contains a slight amount of hydrogen peroxide, such water might be seen as causing a reaction with catalase.

-possible contaminant in the water causing a reaction

-you must complete the experiment again to verify your results

Explanation:

The enzyme catalase is present in all living organisms and it functions in the breakdown of the hydrogen peroxide into water (H2O) and oxygen gas (O2).

Catalase is specific to hydrogen peroxide. Catalase and water reaction is seen in the lab test because there is the possibility of water contamination and maybe the reaction is not correctly evaluated, so one must complete the experiment again to verify the result.

Hence, the correct options are 2nd and 4th option.

b because they naturally adapt to their environment plz mark brainliest

explanation:

b) the inside picture would look at a very high temperature in a very low ph
