Question

biological causes of an anxiety disorder include, but are not limited to, ____________. genetic influences and chemical imbalances in the brain anxiety sensitivity and pairing neutral stimuli to frightening stimuli our evolutionary history of historically frightening stimuli our capacity of observing, retaining, and replicating behavior

Explanation:

Genetic factors can predispose individuals to anxiety disorders. Chemical imbalances (e.g., serotonin, dopamine) in the brain are biological mechanisms linked to anxiety. The other options involve psychological (anxiety sensitivity, pairing stimuli) or observational learning (observing, retaining, replicating behavior) concepts, not biological causes. Evolutionary history of stimuli is more of an evolutionary psychology aspect rather than a direct biological cause like genetics and brain chemistry.

Answer:

genetic influences and chemical imbalances in the brain
