If methylene blue dye is added to a suspension of yeast cells, living cells do not take up the stain, and they remain colourless. However, dead cells are stained blue. This fact was used to carry out an investigation into the rate at which yeast cells were killed at two diff erent temperatures (at high temperatures the yeast enzymes will be denatured). The results are shown in the diagram below.

Which of the following is correct?
