Question 1

Which of the following best describes the role of the wolf in the life cycle of the tapeworm shown in the image?

Accepted Answer

The wolf is the definitive host, where sexual reproduction occurs.

Question 2

Based on the diagram, which host harbors the sexually reproducing stage of the tapeworm?

Accepted Answer

The wolf

Question 3

In the tapeworm life cycle, what is the primary function of the intermediate host (deer)?

Accepted Answer

To harbor the asexual reproductive stage of the parasite

Question 4

If a human ingests eggs from the environment, as shown in the diagram, what role does the human play in the tapeworm life cycle?

Accepted Answer

Intermediate host

Question 5

Which of the following statements about the tapeworm life cycle is correct?

Accepted Answer

Eggs are released into the environment by the definitive host.

Question 6

Suppose a mutation prevents the tapeworm from forming cysts in the intermediate host. What is the most likely consequence for the parasite's life cycle?

Accepted Answer

The parasite will be unable to infect the definitive host.

Question 7

Which of the following best explains why the tapeworm requires both an intermediate and a definitive host?

Accepted Answer

Each host provides a different environment necessary for different stages of the parasite's development.

Question 8

If a population of wolves is eliminated from an ecosystem, what is the most likely effect on the tapeworm's life cycle?

Accepted Answer

The tapeworm's life cycle will be interrupted, preventing sexual reproduction.

Question 9

Which of the following is a correct sequence of events in the tapeworm life cycle as shown in the diagram?

Accepted Answer

Eggs are ingested by the intermediate host, larvae form cysts, definitive host ingests cysts, adults develop and release eggs.

Question 10

Which of the following best describes the process of asexual reproduction in the tapeworm life cycle?

Accepted Answer
