o whitening teeth
o straightening teeth
question 54
which mineral can be sourced from organ meats?
o copper
o fluoride
o iodine
o selenium

Explanation:

• Question 52: Nuts are a good dietary source of zinc. Whole grains have some zinc but are often refined which reduces zinc content. Iodized salt provides iodine. Tea has very little zinc.
• Question 53: An orthodontist specializes in straightening teeth. Cleaning teeth is mainly done by dental hygienists. Strengthening teeth can be part of general dentistry (e.g., with fluoride treatments). Whitening teeth is a cosmetic dental procedure not specific to orthodontics.
• Question 54: Organ meats are a good source of copper. Fluoride is mainly from water fluoridation and some dental products. Iodine is from iodized salt and seafood. Selenium is found in Brazil nuts, seafood, etc., but organ meats are a better source of copper.

Answer:

• Question 52: nuts
• Question 53: straightening teeth
• Question 54: copper
