A scientist predicts that the DNA molecule of the virus contains its genetic material A scientist concludes that some viruses contain DNA within their protein shells. A scientist observes that viruses are composed of a DNA molecule contained in a protein s A scientist proposes that the protein shell of the virus contains its genetic material Ma

Solution

A hypothesis is defined as a supposition or proposed explanation prepared on the basis of limited evidence as a starting point for further investigation. It is an idea or explanation which can be tested through study and experimentation.

We know that a virus contains genetic material either a DNA or RNA, enclosed by a protein coat or shell called capsid.

The first statement is a mere prediction that the DNA molecule contains genetic material. It may not be based on any solid investigation.

The second statement is a conclusion which may be based on already conducted work   and may not be true.

The third statement is the observation of the fact based on some solid evidence or research study.

The fourth statement is the proposition that the protein shell contains the genetic material.

It may or may not be true. Only through an organised investigation or study, the validity of the statement can be proved. So until then it remains as a hypothesis.
