    In a negative feedback mechanism, ADH is the equivalent to the "thermostat" in your home heating system.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    ADH (antidiuretic hormone) is not the equivalent to the "thermostat" in a home heating system. In a negative feedback mechanism, ADH acts as a regulator of water balance in the body by controlling the reabsorption of water in the kidneys. The "thermostat" in a home heating system, on the other hand, regulates the temperature by turning the heating on or off based on the desired temperature setting. Therefore, the statement is false.

    Which of the following imaging devices would best localize a tumor in a person's brain? 

    • A.

      X ray

    • B.

      DSA

    • C.

      PET

    • D.

      MRI

    Correct Answer
    D. MRI
    Explanation
    An MRI (Magnetic Resonance Imaging) device would best localize a tumor in a person's brain. MRI uses strong magnetic fields and radio waves to generate detailed images of the brain, allowing for clear visualization of tumors and other abnormalities. X-ray and DSA (Digital Subtraction Angiography) are not ideal for imaging the brain, as they primarily capture images of bones and blood vessels respectively. PET (Positron Emission Tomography) can detect metabolic activity in the brain but may not provide as precise anatomical details as an MRI.
