Scientists are studying the effects of two chemicals on high blood pressure.When chemical A is used,blood pressure decreases by 20%.When chemical B is used,blood pressure decreases by 40%.When both chemical A and chemical B are used,blood pressure decreases by 35%.The effect of the chemical interaction is _________________.

Question

When both chemicals are used together, the observed effect (35% decrease in blood pressure) is less than what would be expected if the effects of chemicals A and B were simply added together (20% + 40% = 60% decrease in blood pressure). This suggests that the interaction between chemicals A and B is antagonistic, meaning that they "work against" each other in some way.
