Final answer:
Emotions are subjective experiences that consist of physiological arousal and cognitive appraisal. They can be intense and are influenced by various factors such as personal experiences, culture, and biology.
Step-by-step explanation:
Emotions are subjective experiences that consist of physiological arousal and cognitive appraisal. They result from the combination of subjective experience, expression, cognitive appraisal, and physiological responses. Emotions are typically intense and occur in response to something we experience, while mood refers to a prolonged, less intense affective state that does not occur in response to something we experience. Emotions are not always easily controlled, as they can be influenced by various factors such as personal experiences, culture, and biological factors.
