Zombie Ants

What is the main effect of the Ophiocordyceps fungus on ants?

• It changes their color.

• 
  It makes them act like zombies.

• It makes them fly.

• It makes them grow larger.

Why do researchers use a control group in experiments?

• To make the experiment more expensive.

• 
  To confuse the participants.

• To have a baseline for comparison.

• To increase the number of variables.

What chemical is similar to the one produced by the Ophiocordyceps fungus?

• Aflatrem

• 
  RNA

• Acetone

• Phosphate Buffered Saline

What behavior do ants exhibit when affected by aflatrem?

• They dig tunnels.

• 
  They swim.

• They fly.

• They stagger and walk clumsily.

What is the purpose of the Ophiocordyceps fungus making ants climb to a high place?

• To protect the ants from predators.

• 
  To spread its spores more effectively.

• 
  To make the ants stronger.

• 
  To help the ants find food.

What happens to ants' movement as the amount of aflatrem increases?

• They dig deeper.

• They start flying.

• They move more slowly.

• They move faster.

What is one of the effects of aflatrem on ants' genes?

• It changes their color.

• 
  It makes them glow in the dark.

• 
  It makes them immune to other fungi.

• 
  It affects genes responsible for muscle control.

What is the role of RNA in the study of aflatrem's effects on ants?

• 
  It makes ants immune to the fungus.

• 
  It carries instructions from DNA to make proteins.

• It helps ants fly.

• 
  It changes the ants' color.

What might happen to an ant colony if many ants become infected with Ophiocordyceps at the same time?

• The colony might become stronger.

• 
  The ants might become immune to all fungi.

• The colony might collapse due to loss of workers.

• The ants might start flying.

What did researchers dissolve aflatrem in for their experiments?
