Virginia Biology SOL Module 4 bacteria, viruses, and disease overview quiz quiz

It can only reproduce in water

It has ribosomes but no genetic material

It lacks the cellular machinery to make proteins and copy itself

It is a kind of bacterium

Ribosomes and their own metabolism

A protein coat

Genetic material

The ability to evolve

Antibiotics only work in water

Viruses are not cells and lack the structures antibiotics target

Viruses are too large

Viruses have thicker cell walls

By making antibodies

By binary fission (asexual division into two identical cells)

By meiosis

Only inside a host cell

Acting as decomposers that recycle nutrients

Causing food poisoning

Destroying host cells

Spoiling food

All diseases are inherited

Many diseases are caused by microorganisms (pathogens)

Diseases are caused by bad air

Diseases cannot be prevented

Eating a balanced diet

Exercising

Droplets from coughing and sneezing

Inheriting a gene

A protein the body makes to fight infection

A type of white blood cell

A vaccine

A molecule on a pathogen that the immune system recognizes as foreign

Carry oxygen in the blood

Provide energy to the pathogen

Replace damaged DNA

Bind specifically to an antigen and mark the pathogen for destruction

Antibodies last forever in the blood

The pathogen becomes weaker

The skin becomes thicker

Memory cells from the first exposure respond quickly

It contains ready-made antibodies that last for life

It kills all bacteria in the body

It introduces a harmless antigen so the body makes antibodies and memory cells without disease

It replaces the immune system

They sit at the boundary: they have genetic material and evolve but are not cells and cannot reproduce without a host

They are clearly fully alive like bacteria

They are identical to animal cells

They are nonliving and contain no genetic material
