<span>The answer is a graduated cylinder.

Graduated cylinders are used for volume measurement. To determine the volume of irregular shaped tool, such as a metal bolt, the displacement method is useful. Therefore, the graduated cylinder is filled with water. The metal bolt is then placed into the cylinder. It will displace the water, so the difference in the volume, before and after the bolt is placed, is actually the volume of the metal bolt.</span>

Answer:

The one treated with DNase and protease

Explanation:

<em>The samples that will transform yellow into purple if RNA is the genetic material are the ones treated with </em><em>DNase </em><em>and </em><em>protease</em><em> respectively.</em>

<u>The treatment of the heat-killed sample of the purple life with DNase will ensure that the DNA in the sample becomes degraded while treatment with protease will ensure that protein is degraded, leaving only the RNA. Thus, the RNA can be taken up by the yellow life form and become transformed into purple if indeed RNA is the genetic material.</u>

The sample treated with RNase cannot transform the yellow life into purple because the RNase catalyzes the degradation of RNA into smaller components.
