If you have set your quiz for a single attempt and left the "Available Until" date open, then students can review it for the duration of the term without having another opportunity to submit.
If you have set a limited number of attempts (more than one, but not unlimited) and all students have completed all their allotted attempts and availability is open, then students can view the quiz and not reattempt.
I always leave my "Available until" dates open, so that students can use my quizzes for review.
