Using a specific evidence of thermoregulation to support the statement that “The importance of the effect of temperature on physiological function is revealed by adaptations to maintain function at different temperatures”. How exactly is thermoregulation involved as an adaptation?
Consider a scenario in which a person is on a diet and is eating far less each day than dictated by their set point. Describe both the glucostatic theory and the lipostatic theory, explain why someone might be motivated to eat, both in the short-term and over the long-term, make sure to include an explanation of the hypothalamus and its role in monitoring the set points.
