Question

Based on the conditions of early Earth, what conclusion can you draw about the amount of anaerobic respiration that was occurring at Earth’s beginning? Explain your answer.

Answer 1

it does depend on what they mean by "Earth's beginning" I mean too hot and their would have been no life to respire, anaerobic or otherwise :P but I'm not sure if you're supposed to be considering this. At the dawn of 'land' I would have thought that the earth would have been that hot..

Wikipedia says for the Paleocene–Eocene Thermal Maximum (which was the earliest thing I could find):
"temperature increases would have been greatest at the poles, which reached an average annual temperature of 10 to 20 °C (50 to 68 °F); the surface waters of the northernmost[8] Arctic ocean warmed, seasonally at least, enough to support tropical lifeforms requiring surface temperatures of over 22°C"

But that's just the poles so it would have been pretty hot elsewhere.. though I'm not sure if it would have reached 60. Anyway you would be correct in saying that it was hotter than 35deg for parts of Earth so fermentation would be slower.

Answer 2

does that help

Answer 3

Yeah it does thanks :)
