Answer:
The correct answer would be - option D. perform anaerobic respiration in the absence of oxygen.
Explanation:
Yeast is a facultative anaerobic single-cell organism that can live without oxygen. If yeast cells did not get the oxygen they use anaerobic respiration to get the energy.
If the baker activates these cells and stops them to get oxygen the yeast cells have to switch to anaerobic respiration to survive and produces ethanol and releases carbon dioxide.

The action potential has three main stages: depolarization, repolarization, and hyperpolarization. Depolarization is caused when positively charged sodium ions rush into a neuron with the opening of voltage-gated sodium channels.
Question:
<em>What is Darwin’s theory of the origin of species?</em>
Answer:
<em>The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.</em>
Hope this helps!
