The germs from her hands mixed with those in the petri dishes and some were contaminated
Answer:
The amount of peroxidase will be changed by changing the amount of turnip extract used.
Explanation:
A) Adding more or less buffer to the test tube.
<em>B) Changing the amount of turnip extract used.</em>
C) Adding different amounts of water to the mixture.
D) Using different types of turnip extracts prepared for us.
Peroxidase is an enzyme that degrades hydrogen peroxide (H₂O₂), releasing oxygen at the end of the reaction. One of the vegetable sources to obtain peroxidase is turnip (Brassica Napus).
The experiment on which the question is asked has to do with the reaction in which H₂O₂ participates, as a substrate, and the turnip extract containing the enzyme peroxidase, with a change in color due to the release of oxygen.
It is clear that, if the amount of turnip extract in the reaction is changed, the amount of peroxidase added will change.

Answer:
A. Archaea / Bacteria
Explanation:
Bacteriorhodopsin is a protein used by Archaea, most notably by halobacteria, a class of the Euryarchaeota. It acts as a proton pump; that is, it captures light energy and uses it to move protons across the membrane out of the cell
Bacteriorhodopsin is an integral membrane protein usually found in two-dimensional crystalline patches known as "purple membrane", which can occupy up to nearly 50% of the surface area of the archaeal cell.
Proteorhodopsin also known as pRhodopsinbis a family of over 50 photoactive retinylidene proteins, a larger family of transmembrane proteins that use retinal as a chromophore for light-mediated functionality, in this case, a proton pump
