Which of the following best describes cell communication processes that occur when a cell detects a signaling molecule? A. The cell produces hormones that convert the molecule to an electric signal that is detected by relay molecules
B. The cell releases an enzyme that binds the molcule to receptors, allowing the molcule to enter the cell
C. The molecule binds to a receptor protein, which changes the protein and triggers signal transduction
D. The molecule enters the cell through an ion channel and activates a cellular response by inhibiting tranduction

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
