Gene is investigating what makes bread moldy. He put two identical slices of bread on separate plates. He made one slice moist and kept the other slice dry. He left the uncovered plates on a table for 2 hours. Then, he sealed them in plastic bags and put them in a dark, warm place. He looked at them each day for five days. After five days, he observed that 50 percent of the moist slice was moldy, and none of the dry slice was moldy. If Gene observed the slices for three more days, what would he most likely observe?
