Which statement is the best example of - a synergistic interaction?
A) The combined effects of alcohol and a depressant produce a greater effect than would be expected from adding their individual effects.
B) When the exponential growth of the human population exceeds the carrying capacity, a massive dieback will occur.
C) The use of alcohol reduces the effectiveness of a blood thinner.
D) Secondary smoke may increase chances of lung cancer in a nonsmoker.
Synergistic Interaction
A phenomenon where combined actions of different elements produce an effect greater than the sum of their separate effects.
Exponential Growth
Rapid increase in a quantity where the rate of growth is proportional to the current size, leading to ever-larger increases over time.
Carrying Capacity
The maximum population size that an environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.

Final Answer :
A
Explanation :
A synergistic interaction occurs when two or more substances or factors combine to produce an effect greater than the sum of their individual effects. In option A, the combined effect of alcohol and a depressant is greater than the effect of adding their individual effects, indicating a synergistic interaction. Option B describes a situation of overpopulation and resource depletion, which is not an example of a synergistic interaction. Option C describes an antagonistic interaction, where the use of alcohol reduces the effectiveness of a blood thinner. Option D describes a situation where one factor (secondary smoke) increases the risk of a disease (lung cancer), which is not a synergistic interaction.
