Question

how can a liquid be drawn into a pipette safely? by squeezing and releasing a bulb attached to the wide end of the pipette by gently sucking the wide end of the pipette until the liquid rises up by using a beaker to pour the liquid into the pipette by using an eyedropper to drip the liquid into the pipette

Explanation:

A pipette is a common laboratory tool for handling liquids. Squeezing and releasing a bulb attached to the wide - end of a pipette creates pressure differences that draw the liquid into the pipette safely. Pouring with a beaker is not a safe or accurate way to fill a pipette, and using an eyedropper to drip liquid into a pipette is not the standard method. Sucking liquid directly into a pipette by mouth is dangerous.

Answer:

by squeezing and releasing a bulb attached to the wide end of the pipette
