Radioactive iodine (iodine-131) is used to treat some thyroid conditions. Why does it reach the thyroid?

  1. AThe thyroid gland takes up iodine to make its hormones
  2. BRadiation is always drawn toward the head
  3. CIodine is strongly attracted to the metal ions stored in the neck
  4. DIodine-131 is not radioactive inside the body
6.Medium

  1. A0
  2. B4
  3. C2
  4. D1
7.Hard

Ethanol (CH₃CH₂OH) and dimethyl ether (CH₃OCH₃) have the same formula, C₂H₆O, but ethanol boils at a much higher temperature. Why?

  1. AEthanol has an O–H group, so its molecules form hydrogen bonds with each other
  2. BDimethyl ether is ionic and ethanol is covalent
  3. CEthanol molecules are heavier than dimethyl ether molecules
  4. DEthanol has more carbon atoms
8.Hard
