Q: How is anaerobic respiration affected by changes in temperature?
A: It is affected by temperature change, when the temperature rise it increase the rate of the anaerobic respiration, up to point. Soon the heat will start putting a lot of stress of the organism and then the rate of the anaerobic respiration will go down, more rising in temperature will eventually kill the organism.
Q: 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.
A: The atmosphere of early Earth was made up with almost of different nitrogen gases, water vapor and carbon dioxide. There wasn't any pure oxygen or I should say there wasn't any breathable oxygen in the air in those days. The first form on earth had to develop in the absence of oxygen using the anaerobic respiration. All the cells used this method to develop and reproduce. They used sunlight, water and carbon dioxide to live and the waste product was oxygen. This oxygen was pure and richer than the anaerobic life form, this causes the anaerobic life forms to look for places that doesn't have little or no oxygen, such as in the deeper regions of the oceans or in soil, because the oxygen was toxic. So in the beginning there was only anaerobic atmosphere then it became aerobic.
Q:If there was a sudden drop in temperature after the evolution of the first living cells, predict how that might have affected the changes in the atmosphere and the evolution of Cyanobacteria and other autotrophs. Explain your answer
My prediction would have to include the data from the graph. The question doesn't exactly include any temperature so I can base my hypothesis on so I conclude that if the temperature suddenly dropped to 30 degrees Celsius to – 20 degrees Celsius, the
