Correct Answer: B

Rationale: The correct answer is B: The ability to maintain a stable internal environment. Homeostasis is the body's ability to regulate and maintain a stable internal environment despite external changes. This includes maintaining stable levels of temperature, pH, and nutrients. Choice A is incorrect because homeostasis is not solely about body temperature. Choice C is incorrect as it does not encompass the overall concept of homeostasis. Choice D is incorrect because although regulating blood glucose levels is part of homeostasis, it does not fully capture the broad scope of maintaining a stable internal environment.

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: B

Rationale: The correct answer is B: Cardiac muscle. Cardiac muscle is found exclusively in the heart, allowing it to contract rhythmically and involuntarily to pump blood throughout the body. Smooth muscle (A) is found in organs like the intestines and blood vessels, not in the heart. Skeletal muscle (C) is attached to bones and responsible for voluntary movements, while voluntary muscle (D) is a general term that refers to skeletal muscle controlled voluntarily. Therefore, the unique characteristics of cardiac muscle make it the correct answer for this question.

Correct Answer: B

Rationale: The correct answer is B: Liver. The liver is responsible for detoxifying chemicals and metabolizing drugs due to its enzymes that break down substances. It also helps in excreting waste products. The kidneys (A) filter blood and regulate fluid balance. The heart (C) pumps blood throughout the body. The pancreas (D) produces digestive enzymes and insulin. Thus, the liver is the primary organ involved in detoxification and drug metabolism.
