E. coli was incubated with aeration in a nutrient medium containing two carbon sources, and the following growth curve was made from this culture. a. explain what happened at the time marked x. b. which substrate provided "better" growth conditions for the bacteria? how can you tell?

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.

i do believe the correct answer would be the third one. location c, because earth is tilted away from the sun at this time

hope this
