According to one side of the viral debate, what should viruses be called since they are unable to multiply independently?

• Living organisms

• Infectious molecules

• Bacteria

• Parasites

Which statement best describes how viruses are viewed by those who consider them living organisms?

• Viruses can reproduce on their own.

• Viruses direct life processes in the cells they infect.

• Viruses are always dead outside a host.

• Viruses are a type of bacteria.

What terminology is suggested as more accurate than "alive" or "dead" when describing viruses?

• Dormant or active

• Active or inactive

• Living or non-living

• Growing or shrinking

Approximately how large are the smallest viruses, parvoviruses, in diameter?

• 20 nm

• 100 nm

• 150 nm

• 450 nm

Explain why understanding the size differences between viruses, bacteria, and eukaryotic cells is important in microbiology.

• It helps in designing appropriate filters and treatments.

• It is only useful for artistic purposes.

• It determines the color of the organisms.

• It is not relevant to any scientific study.

What is the core of all viruses composed of?

• Only proteins

• DNA or RNA

• Lipids

• Carbohydrates

Which term refers to the combination of the viral core and its protein coat?

• Envelope

• Nucleocapsid

• Plasmid

• Cytoplasm

What is the envelope in some viruses made from?

• The virus's own DNA

• The host's cell membrane

• The virus's ribosomes

• The host's cytoplasm
