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.

Pls me i need this ! each cell has genes activated depending on it's job and what kind of cell it is. it is the presence of that causes the repressor protein to fall off and unblock the gene on the lac operon. if a gene is turned on then it is being an additional circular chromosome found in some bacteria that is used in genetic engineering.
