The answer is c because it’s none of those
The correct answer is: Rinsing with alcohol during the washing step stripped the bacteria off the glass slide.
The sample may be lost during laboratory preparation. Usually the errors occur during the heating step (due to overheating or insufficient heating).
Answer:
For every molecule of O2 that is released by photosystem II,<u> 2 </u>H2O molecules are needed, which together pass <u>4</u> electrons to the PS II reaction-center complex.
Explanation:
Photosystem II can be described as a protein complex through which oxygen is released using water. Light energy is used in this process hence termed as light dependent reactions. This reaction happens in the thylakoid regions. As a molecule of water contains 2 hydrogen atoms, hence a molecule of H2O will release two electrons. two molecules of H2O will release 4 electrons. The break down of water also results in the release of oxygen.
