Final answer:
Hormones can influence the intensity and frequency of emotions by binding to specific receptors on target cells and modulating signaling pathways, thus affecting mood and emotional responses. So the correct answer is option (C).
Step-by-step explanation:
The relationship between hormones and emotions can be summarized as follows: Hormones can influence the intensity and frequency of emotions (option c). This is because a hormone is released in response to a stimulus, it travels through the body and then binds to receptors of the target cell to elicit a response. This can include changes in mood and emotional state.
Hormones, such as those released by the pituitary gland or other endocrine glands, mediate changes in target cells and can stimulate signaling pathways in the presence of hormones. These pathways can affect physiological processes, including mood and emotions. Therefore, while hormones do not directly cause specific emotions, they can certainly modulate how emotions are felt and how the body responds to emotional stimuli.
