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 |
Solution
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 ..
