Answer:
The process that does not require oxygen is fermentation.
Explanation:
Fermentation is an alternative route of cellular respiration for obtaining energy, in the absence of oxygen. In aerobic respiration, oxygen is the acceptor of electrons from NADH but, in anaerobic respiration, the electron acceptor is an organic compound.
The fermentation process does not occur in the mitochondria nor does it involve the electron transport chain, and has a low energy yield at the end of the process.
With respect to the other options:
- <em>The </em><em><u>electron transport chain</u></em><em> and the </em><em><u>Krebs cycle</u></em><em> occur in the presence of oxygen.</em>
Answer:
They are likely to have evolved from similar ancestors.
Amino acids are generally soluble in water, meaning that they do dissolve in water.
The correct answer is: e. the stage and the objective lens.
Coarse Focus is the rough focus knob on the microscope used for the movement the of objective lenses toward or away from the specimen (located on the slice that is placed on the stage). On the other hand, fine focus is used to focus on various parts of the specimen.. Generally, coarse focus is used first to get close then moves to the fine focus knob for fine tuning.
