long hair should always be tied back when working in the lab.

Explanation:

In a lab, broken, chipped or cracked glassware is a safety hazard. Switching it with another group's equipment is unethical and dangerous, putting others at risk. Putting it back and not telling anyone or using it anyway also pose risks of injury. Notifying the teacher for replacement is the proper and safe procedure. For long - hair in the lab, it can get caught in equipment or come in contact with chemicals, so tying it back is a standard safety measure.

Answer:

Question 9: d) notify your teacher so it can be replaced.
Question 10: True (assuming this is a true - false question as the statement is a standard lab safety practice)
