Answer:

Janet is watching an RNA virus.

Explanation:

Viruses are microorganisms classified according to their DNA or RNA nucleic acids. They are formed by a protein capsule, the capsids and, inside this, there is only DNA or RNA. Accordingly, we can say that Janet is observing an RNA virus under the microscope.

Some viruses are called enveloped because they have the capsid formed by a lipid membrane resulting from the invaded cell plasma membrane.  The capsule is also responsible for the specificity of the virus to adhere to certain cells, this is only possible because they have membrane proteins (receptors) that can fit into their proteins.

Answer:

The correct answer will be virus.

Explanation:

The virus is the infectious agents which cannot replicate themselves. these viruses contain a protein capsid surrounding the genetic material.

The genetic material in the virus could be DNA or RNA but do not have both as single-stranded or double-stranded forms.  

A virus with RNA are common in nature and an only a limited amount of RNA or DNA can fit a capsid and the capsid along with genetic material is known as the nucleocapsid.  

Since the specimens show RNA but not DNA it is a virus-like Ebola, polio, measles, therefore, the specimen is virus and is the correct answer.

We may feel hot but that's because we are hot from the heat of something. If we didn't sweat then our temperature would become very high and we would die.</span>
