Question

((11.)) select all tools that are used measure length
a meter stick
b burets
c caliper
d pipettes
e micrometer
((37.)) identify the following laboratory symbol

Explanation:

A meter - stick is a common tool for measuring length. A caliper can precisely measure the dimensions (including length - related measurements like diameter, thickness etc.). A micrometer is used for very precise length measurements at a small scale. Tongs are used for handling objects, not measuring length. Pipettes are used for measuring and transferring volumes of liquids, not length.

Answer:

A. A meter - stick, C. caliper, E. micrometer
