Final answer:
The subject of a sentence is what it is about, while the predicate provides more details and includes the verb.
Explanation:
The subject is typically what the sentence is about, while the predicate includes the verb and gives more information about the subject. In the sentence 'Holly injured her rear on a spiky cactus,' Holly is the subject as it tells us who the sentence is about, and injured her rear on a spiky cactus is the predicate as it describes the action.
