Hairworms and Their Unique Genetics

What makes hairworms' genetic shortcoming unique compared to other parasites?

• They can produce cilia.

• They have more chromosomes.

• They lack a significant portion of genes.

• They have extra genes.

Where do most hairworms spend their time?

• On mountain tops.

• In the desert.

• Inside other creatures.

• In the ocean.

What crucial cell structure are hairworms missing?

• Cilia

• Nucleus

• Mitochondria

• Ribosomes

Why is the absence of cilia in hairworms surprising?

• Cilia are not important for any organism.

• Cilia are crucial for sensory systems in animals.

• Cilia are only found in plants.

• Cilia are not found in any other parasites.

How do hairworms manage to survive without cilia?

• They don't need to move.

• They use cilia from their hosts.

• They have other unique genes.

• They live in water.

What phase do hairworms have that is unusual for parasites?

• A flying phase.

• A photosynthetic phase.

• A free-living phase.

• A dormant phase.

What is the main challenge for free-living hairworms without cilia?

• Finding food.

• Finding mates and reproducing.

• Avoiding predators.

• Staying hydrated.

What does the study of hairworms' genes suggest about genetic equipment?

• All genes are equally important.

• Genes are not related to survival.

• Some organisms can survive with fewer genes.

• Organisms can't lose any genes.

What is ironic about the name 'hairworms'?

• They live in hair.

• They are not worms.

• They have hairless cells.

• They have a lot of hair.
