Which of the following types of protists is most likely to have a nerve net?

• A. Amoebas
• B. None of the above
• C. Choanoflagellates
• D. Ciliates

Answer: (B)

Verified step by step guidance

1. Understand the concept of a nerve net: A nerve net is a simple network of neurons found in some animals, such as cnidarians (e.g., jellyfish), that allows for basic responses to stimuli.
2. Recognize that protists are a diverse group of mostly unicellular organisms that do not have complex structures like nerve nets. They are not animals and typically do not have nervous systems.
3. Consider the characteristics of the given protists: Amoebas, choanoflagellates, and ciliates are all types of protists. Amoebas move and feed using pseudopodia, choanoflagellates are flagellated and often colonial, and ciliates use cilia for movement and feeding.
4. Evaluate the likelihood of each protist having a nerve net: Since nerve nets are associated with multicellular animals and none of the listed protists are animals, it is unlikely for any of them to have a nerve net.
5. Conclude that none of the given protists (amoebas, choanoflagellates, ciliates) are likely to have a nerve net, as they do not possess the complex multicellular structures required for such a system.
