Unit 7 Review (Biology)

Front

What are the main components of a typical virus?

Back

A typical virus consists of a protein coat and genetic material.

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

Which organisms are most closely related according to a cladogram?

Back

Organisms that share a more recent common ancestor are considered more closely related.

Front

What is the major difference between viruses and living organisms?

Back

Most living things can reproduce independently, whereas viruses must infect living cells to reproduce.

Front

What is the definition of a genus in biological classification?

Back

A genus is a rank in the biological classification (taxonomy) that is one level above species and one level below family.

Front

Which animal is classified in the same genus as a lion?

Back

The tiger is classified in the same genus (Panthera) as the lion.

Front

What is genetic material?

Back

Genetic material is the substance that carries genetic information in living organisms, primarily DNA or RNA.

Front

How do viruses reproduce?

Back

Viruses reproduce by infecting a host cell and using the host's cellular machinery to replicate their genetic material and produce new virus particles.

Front

What is the role of a protein coat in a virus?

Back

The protein coat, or capsid, protects the viral genetic material and helps the virus attach to and enter host cells.

Front

What is the significance of cladistics in biology?

Back

Cladistics is a method of classifying organisms based on common ancestry and evolutionary relationships, helping to understand the evolutionary history of life.
