The role of Ca2+ ions in the formation of the fertilization envelope and blocking polyspermy can be further studied using Ca2+ channel blockers. As their name suggests, Ca2+ channel blockers block the movement of Ca2+ ions through channels. In the case of gated Ca2+ channels, the channel blockers prevent the channels from opening even if the signal to open is present.

Suppose that you conduct an experiment in which you test whether the fertilization envelope forms and polyspermy occurs under the following conditions:

Control group: An unfertilized sea urchin egg is left untreated (no Ca2+ channel blockers added). Then sperm are added.

Experimental group: Ca2+ channel blockers are added to an unfertilized sea urchin egg. Then sperm are added.

Drag the labels (yes or no) to predict whether or not the following events can occur under control conditions and experimental conditions.
