Step-by-step explanation:
The terms root, prefix, and suffix are related to morphology - the study of words, how they're formed, and their relationship with other words. The root of a word is the word without other morphemes. Prefixes are affixes added before the root, and suffixes are affixes added after the root of the word.
Here, you were given morphemes that form words related to medicine and other fields of science. When you're unsure about what a word means, you can look it up in a dictionary - an alphabetically arranged listing of words that contains different information about them, such as their definitions, examples, origin, and pronunciation. Another tool that could help you is a glossary - a listing of words related to a certain field, e.g. a glossary of medical terms.
