pH
oxygen concentration

Question 7

Over what time period will you measure the size of the gas bubble in the fermentation tube?

5min
20min
as long as you decide.
10min

Question 8

Question 11

Bonus: you'll need to look this up.....first find in the lab manual what macromolecule is abundant in the cell wall of yeast cells. Then look up which very different group of organism also has this macromolecule in their exoskeletons. For an answer I'm looking for the name of that group of organism. Write ONE word as your answer in its plural. That word must have 7 letters. Use no punctuation in your answer ONLY the 7 letters in the word.
