No. Each answer is checked as soon as you choose it, you see the right option straight away, and you cannot go back to change it.
Answers are final. When you choose an option, the server checks it and shows you the right option before you move on to the next question.
The questions come to your browser without their answers, so there is nothing to look up in the page. You also get one attempt per day, so a finished day cannot be replayed (does the Daily Five count toward the streak). For ways to narrow down the options before you commit, see the Daily Five tips.
