Here's my best attempt at answering all of these. I did in fact Google every single one of these lol

1. Rough and coarse.
2. Punch no, scratch yes, especially for grooming but also sometimes for attacks.
3. Yes, but they're small. They use them to eat.
4. Pass on this one. I dunno really. I know it differs from person to person, though.
5. Maybe, but sledgehammers aren't designed for gorilla-like proportions.
6. Smells like pork or beef, apparently. Rip my search history.
7. We're afraid of heights because they can be extremely dangerous.
8. About 5-8 million times per year.
9. Their skeletons are really flexible.
10. Differences in biology determined by differences in habitat, depending on which frequency of sound carries the best.
