DOK Level 1: Recall

How do viruses primarily affect human health?

• By producing toxins

• By destroying host cells

• By competing for nutrients

• By forming biofilms

DOK Level 1: Recall

Explain how the structure of a virus allows it to infect a host cell.

• The capsid protects the viral DNA or RNA

• The tail fibers attach to the host cell

• The envelope helps the virus to fuse with the host cell membrane

• All of the above

DOK Level 2: Skill/Concept

Compare the impact of bacterial infections and viral infections on human health.

• Bacterial infections can be treated with antibiotics, while viral infections cannot

• Both can cause diseases but in different ways

• Bacterial infections are generally more severe than viral infections

• Viral infections are always more contagious than bacterial infections

Tags

DOK Level 2: Skill/Concept

Analyze why antibiotics are ineffective against viruses.

• Antibiotics target bacterial cell walls, which viruses do not have

• Antibiotics disrupt bacterial metabolism, which viruses do not have

• Antibiotics cannot reach viruses inside host cells

• All of the above

Tags

DOK Level 3: Strategic Thinking

Evaluate the role of the immune system in combating viral infections.

• The immune system produces antibodies that neutralize viruses

• The immune system destroys infected host cells

• The immune system remembers past infections to respond faster in the future

• All of the above

Tags

DOK Level 3: Strategic Thinking

Predict the outcome if a virus mutates and becomes resistant to the host's immune response.

• The virus will be easily eliminated by the immune system

• The virus will cause a more severe infection

• The virus will become less infectious

• The virus will stop replicating

DOK Level 3: Strategic Thinking

Explain how bacteria can develop resistance to antibiotics.

• Through genetic mutations

• By acquiring resistance genes from other bacteria

• By producing enzymes that deactivate antibiotics

• All of the above

Tags

DOK Level 2: Skill/Concept

Discuss the importance of vaccination in preventing viral diseases.

• Vaccination stimulates the immune system to recognize and fight viruses

• Vaccination can lead to herd immunity, protecting those who cannot be vaccinated

• Vaccination reduces the spread of viral infections

• All of the above

DOK Level 3: Strategic Thinking

Are microorganisms and microbes same?

• yes

• no
