Take The Flatworm Challenge

Explanation
Flatworms are known for their parasitic feeding habits. They typically attach themselves to a host organism and feed off its nutrients. This parasitic relationship allows the flatworms to obtain the necessary sustenance for their survival and reproduction. They can cause harm to their host, often leading to diseases or other negative effects. Therefore, the correct answer is "Parasitic".

Explanation
The correct answer is "More than 20,000". This suggests that there have been over 20,000 different species of flatworms discovered.

Explanation
Flatworms are able to reproduce both sexually and asexually. They have the ability to reproduce asexually through a process called regeneration, where a new individual can be formed from a fragment of the original worm. This allows them to reproduce quickly and efficiently. Additionally, flatworms can also reproduce sexually, where two individuals come together to exchange genetic material and produce offspring. This allows for genetic diversity and adaptation to changing environments. Therefore, flatworms have the capability to reproduce using both sexual and asexual methods.

Explanation
Flatworms move using cilia, which are tiny hair-like structures that cover their body. These cilia beat in a coordinated manner, creating a wave-like motion that propels the flatworm forward. This movement allows the flatworm to glide smoothly through its aquatic or moist environment. Jetpacks and feet are not mechanisms that flatworms use for movement.

Explanation
Flatworms usually live in both water and bodies of other organisms. They are found in various aquatic environments such as freshwater, marine, and even damp terrestrial habitats. Some flatworms are parasitic and live inside the bodies of other organisms, including humans and animals. This dual habitat makes the answer "Both A and B" correct.

Explanation
Tapeworms, Planaria, and Flukes are all types of flatworms. Flatworms, also known as Platyhelminthes, are a phylum of invertebrates characterized by their flat, ribbon-like bodies. Tapeworms are parasitic flatworms that live in the intestines of vertebrates, including humans. Planaria are free-living flatworms that are commonly found in freshwater environments. Flukes, also known as trematodes, are another type of parasitic flatworm that infect various animals, including humans. Therefore, all three options listed in the answer are correct types of flatworms.
