Question

Some prokaryotes use sulfur or iron instead of oxygen as an electron acceptor. Which of the following does NOT represent a reason why these prokaryotes did not evolve into complex multicellular forms before the atmosphere had a high concentration of oxygen?

Question 6 options:

The concentrations of sulfur and iron are too low to support multicellularity

Cell wall would prevent development of targeted cell-cell communication

Neither sulfur nor iron occurs as a widely distributed gas

Relatively simple genomes do not provide opportunity for sophisticated gene regulation

The concentrations of sulfur and iron are too low to support multicellularity

Cell wall would prevent development of targeted cell-cell communication

Neither sulfur nor iron occurs as a widely distributed gas

Relatively simple genomes do not provide opportunity for sophisticated gene regulation

Explanation / Answer

ANSWER WOULD BE : Neither sulfur nor iron occurs as a widely distributed gas..... BECAUSE SULPHUR AND IRON ARE SOLIDS AND ATMOSPHERIC BREETHING WOULDNT HAVE BEEN POSSIBLE IN MULTICELLULARITY ..
