Answer:

Option B

Explanation:

B. The cell will grow uncontrollably and continue to divide as long as it has food.

Cell growth is theeoretically stimulated by the binding of growth factors to their receptors using signaling pathways.

These pathways are regulated by proteins which are encoded for in the genes.

The gene that controls the regulation of these pathway when mutated produce malfunctioning signaling protein thus not allow for regulations of the cell cycle causing uncontrollable cell division. These mutated genes are called oncogenes.

Cathy placed a sample of yeast , a single celled eukaryotes, in a closed test tube containing a solution of glucose. How will th
maxonik [38]
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 :)
