The cells, organelles, and the tissues of the body are measured in micrometers. The size of the cells, tissues, and various organelles are very small. Majority needs the help of microscope to be seen. Therefore, the larger units of the metric system cannot be used to measure their sizes. Hence, the smaller unit, such as the micrometer is used for their measurement purpose.
The given blank can be filled with micrometers.
Answer:
Explanation:
The first mass extinction is called the Ordovician-Silurian Extinction. It occurred about 440 million years ago, at the end of the period that paleontologists and geologists call the Ordovician, and followed by the start of the Silurian period. In this extinction event, many small organisms of the sea became extinct.
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.
