A) Identify a signaling molecule from the model presented. Explain how receptors play a role in cell
differentiation.
B) Identify the dependent variable and two controls the experimenters used when conducting this
experiment.
C) Evaluate if the number of Variant 1-Type cells with mating projections was significantly different
from those of the Wild Type. Use chi-square analysis.
D) Scientists propose that a mutation has occurred that either changed the mating pheromone or
receptor site on the Variant 1-Type yeast cells. Predict where the mutation occurred. Justify
your prediction with evidence from the experiment and scientific reasoning, based on your
knowledge of cell-signaling pathways.
