I don't see the choices, but I can help explain them to you! :) A Tropical Dry Forest has extremely high temperatures year round and doesn't get as much rain as a tropical rain forest. There tends to be more dry times of the year than wet, but when it rains, it rains a lot. On the other hand though, a Tropical Rain Forest has very humid and a really wet and soggy climate year round. It's extremely rare for this forest not to rain. I hope this cleared some things up for you! Hope this helped! :)
I believe the answer would be C. Because all worms normally have round bodies, and yes, they can be slender. They also don't really have nostrils, they can breathe through their skin even though they don't have lungs. So C. would be the best answer.

The second one is a compound
The third one is molecules that are not compounds
The last one is a atom
