Apopluation fo yeast grows in a tube under ideal condition until it runs out of space in the test tube. which kind of curve would accurately show the changes in this population

You didn't include any graphs but I can try to describe what it should look like. The graph would probably be an exponential curve in the beginning that slows down and begins to flatten out in the end, which is when the population of yeast hits the carrying capacity of the tube and runs out of space. Hope this helps!
