Verified step by step guidance

Understand the concept of homeostasis: Homeostasis refers to the body's ability to maintain a stable internal environment despite external changes. It involves various physiological processes that regulate factors like temperature, pH, and blood pressure.

Identify the signs of disrupted homeostasis: When homeostasis is affected, it can lead to imbalances in the body's systems. Increased blood pressure is a common sign of disrupted homeostasis, often associated with stress or drug abuse.

Analyze the options given: Evaluate each option to determine if it indicates a disruption in homeostasis. A stable body temperature suggests normal homeostasis, while increased blood pressure indicates a potential disruption.

Consider the effects of drug abuse: Drug abuse can lead to various physiological changes, including increased blood pressure, which is a sign of disrupted homeostasis. Enhanced metabolic rate and improved immune response are not typically associated with drug abuse affecting homeostasis.

Conclude with the correct sign: Based on the analysis, increased blood pressure is the correct sign of possible drug abuse affecting homeostasis, as it indicates a disruption in the body's ability to maintain stable internal conditions.
