It's been a while without a response, so I'll go ahead and post the answers:
1. The scolex is the head of a tapeworm, where the tapeworm attaches to the host. It contains a sucker and (usually) hooks. 
2. Strobila
3. Premature
4. Gravid
Anyone can feel free to post the next question.

Note: edited afterwards to hide the answers.
