Final answer:
The root 'tract' fits into both 'pre____' and '____ate' to create 'pretract' and 'tractate'. 'Hypertension' is an example of how anatomical terms are formed with prefixes and roots signifying specific meanings.
Step-by-step explanation:
The correct answer to the question is D.tract. The word root tract can be added to both pre and ate to form the words pretract and tractate.
When looking at the prefixes, bases, and suffixes provided, for instance, combining dis + gest + ion results in the word digestion, where the palatalized sound of [ch] spelled occurs due to the pronunciation of the -tion suffix following gest.
In anatomy, terms are regularly composed of roots, prefixes, and suffixes as in the example of hypertension where the prefix hyper- means “high” or “over,” and the root word “tension” refers to pressure.
