8th Grade Unit 4 Test Review: Disease and Biotechnology

Many infectious diseases have been nearly eliminated worldwide. Why should global studies of infectious diseases continue?

• All infectious disease organisms are fatal.

• All infectious diseases are resistant to any form of treatment.

• All infectious disease organisms have the ability to mutate, adapt, and survive.

• All infectious diseases are caused by viruses that do not respond to antibiotics.

Which needs a host cell in order to reproduce?

• bacteria

• fungi

• protists

• viruses

Which characteristics best describe bacteria?

• cause influenza, can reproduce easily, nonliving

• unicellular, microscopic, treated with antibiotics

• multicellular, larger than animal cells, do not reproduce

• require a host cell to multiply, found in the soil, treated with vaccines

Which graph best represents bacterial growth?

• 
• 
• 
• 

Which illness could most likely be treated with antibiotics?

• influenza

• common cold

• strep throat

• diabetes

What is the purpose of antibiotics?

• They are used to treat viral infections.

• They are used to treat bacterial infections.

• They are used to induce immunity to disease.

• They are used to treat the symptoms of disease.

Which best describes a negative result from the use of antimicrobial soaps?

• extinction of bacterial strains

• decreased resistance to viral pathogens

• evolution of resistant bacterial strains

• increased allergenic reactions to antibiotics

Although antibiotics are useful in the control of bacteria, which best describes the disadvantage from their overuse?

• The overuse of antibiotics could lead to pollution of water resources.

• The overuse of antibiotics could lead to resistant strains of bacteria.

• The overuse of antibiotics could lead to the spread of mutated diseases.

• The overuse of antibiotics could lead to weakened immune systems in humans.

What is the most likely result of overusing a particular antibiotic?

• fewer infections caused by bacteria resistant to the antibiotic

• more infections caused by bacteria resistant to the antibiotic

• fewer infections caused by viruses and bacteria

• more infections caused by viruses

Which reproductive body of fungi is released, aiding in the spread of fungal infections?

• eggs

• pollen

• sperm

• spores
