Question 31 Which of the following statements is true about the root of the medical term?...
Question 31 Which of the following statements is true about the root of the medical term? Medical terms have only one root. Adding a prefix at the end of the word modifies the root of the word to give it new meaning. The root is the foundation or core of the medical term. The root is derived from the Chinese language. Medical terms do not have suffixes attached to the root Question 32 Which of the following statements is true...
