Mitochondria are tiny organelles inside cells that are involved in releasing energy from food.This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell. Cells that need a lot of energy, like muscle cells, can contain thousands of mitochondria.
I think that the answer is A.) prey
Yeast is very similar to human cells in that we have the same cellular respiration process. The formula for cellular respiration is C6H12O6(Glucose) + O2(Oxygen) = CO2(Carbon dioxide) + H2O
Because of this we know that the yeast is going to take oxygen from the air and the glucose in the test tube and produce carbon dioxide with it, so the full answer would be “The composition of the air in the test tube would change so that there is a higher composition of CO2.” If you need to explain it more pull from my explanation :)

Topsoil is the part of a soil profile that is made up of partly weathered rock.
Hope this helps :)
