• They grow

• They digest food

Multiple Choice

Viruses can reproduce on their own

• False

Multiple Choice

A virus is considered non-living because...

• They do not have DNA

• It does not have all the characteristics of life

• They can't evolve

• They make you sick

Multiple Choice

What part of a virus houses the genetic material (DNA/RNA)?

• tail

• nucleus

• capsid

• lipid

Multiple Choice

Which best describes the basic structure of a virus?

• nucleic acid strand surrounded by a protein coat

• a tail surrounded by a protein coat

• a tail surrounded by a carbohydrate coat

• nucleic acid strand surrounded by a carbohydrate coat

Multiple Choice

A(n) _____ is a virus that enters a bacterial cell.

• endospore

• decomposer

• plasmid

• bacteriophage

Drag and Drop

Multiple Choice

What is the main function of the surface markers on a virus?

• They aid in respiration

• They help the virus grow

• They help the virus invade its host by attaching to specific sites on the host

• They help the virus digest food molecules

Multiple Choice

What is the first step of the virus reproduction cycle?

• The viruses genetic material (DNA) starts to take over the functions of the cell

• The host cell bursts open, releasing the new viruses

• The virus injects its genetic material into the cell

• A virus attaches to the surface of a host cell
