Problem:
Given that stress responses can be beneficial in some environments but are also linked with significant costs, what type of selection would be expect to act on population levels stress neurotransmitter levels? Group of answer choices Stabilizing (selection against extremely low or high stress neurotransmitter levels) Directional (selection for either very high or low stress neurotransmitter levels) Disruptive (selection for both very high and low stress neurotransmitter levels with selection against moderate levels)
