Question 1 of 5
A newly developed pesticide has been observed to bind to an intracellular hormone receptor. If ingested, residue from this pesticide could disrupt levels of .
Correct Answer: B
Rationale: Step-by-step rationale for why choice B (thyroid hormone) is correct: 1. Thyroid hormone is a key hormone that regulates metabolism and growth. 2. Intracellular hormone receptors are specific to certain hormones. 3. Disruption of thyroid hormone levels can lead to metabolic disorders. 4. Pesticide binding to the thyroid hormone receptor can interfere with its normal function. Summary of why other choices are incorrect: A: Melatonin regulates sleep-wake cycles, not metabolism. C: Growth hormone regulates growth and development, not metabolism. D: Insulin regulates blood sugar levels, not metabolism.
Question 2 of 5
Which division of the nervous system sends signals to the adrenal glands during moments of danger?
Correct Answer: B
Rationale: The correct answer is B: Sympathetic division. This division of the autonomic nervous system is responsible for the body's "fight or flight" response during moments of danger. When an individual perceives a threat, the sympathetic division activates to prepare the body for action, including sending signals to the adrenal glands to release adrenaline and cortisol, which help increase heart rate, blood pressure, and energy levels. The other choices are incorrect because: A: The central nervous system consists of the brain and spinal cord, which are responsible for processing and transmitting information within the body, but it does not directly send signals to the adrenal glands. C: The parasympathetic division is responsible for the body's "rest and digest" functions and works in opposition to the sympathetic division. It does not send signals to the adrenal glands during moments of danger. D: The peripheral nervous system consists of nerves outside the brain and spinal cord, including sensory and motor nerves, but it does not specifically send signals
