Which best describes proper disposal technique?
a bin should be labeled "chemical wastes and hazardous waste."
a bin should be labeled "chemical wastes and broken glass."
students should know proper disposal of the chemicals they use,
students can dispose of all chemicals in the sink.

The correct answer is A. Proper disposal technique is very important because there are different types of waste. Chemical waste is very hazardous as it may cause reaction to the skin if touched or not stored properly. Chemical compatibility with the disposal bin must also be considered.

fumikage isn't really a bird, and tsuyu does have teeth. tsuyu has a transformation quirk which still allows her to be partially human. otherwise we'd have a large frog running around. fumikage has teeth because again, he isn't a bird. his head was a quirk mixture if i'm correct.
