1. Round worms make up the largest phylum of worms, the phylum Nematoda. To arrive at this answer, you can start by understanding that round worms belong to a specific group of animals called worms. The largest phylum refers to the largest group or category within the classification system. By searching for "largest phylum of worms," you can quickly find that it is the phylum called Nematoda.
2. Many nematodes are parasitic, but most are free-living. The answer to this question requires some knowledge about nematodes. Firstly, understanding that nematodes are a type of roundworm will help. Then, by searching for their characteristics, you can find that many nematodes are indeed parasitic. However, when considering the total number of nematode species, only a small percentage is actually parasitic. The majority of nematodes are free-living, meaning they do not rely on a host organism for survival.
3. Wastes leave the body of a roundworm through an opening at the end of the digestive tract called the anus. This question can be answered by having a basic understanding of the anatomy of roundworms. The digestive tract is a system that processes food and eliminates waste. The anus is the opening at the end of the digestive tract through which waste materials, such as feces, are expelled from the body.
4. Humans get hookworm infections by walking barefoot over dirt or through fields. This question relates to a specific parasitic infection called hookworm. By searching for "how humans get hookworm infections," you can find that one common way of transmission is through direct contact with contaminated soil. Walking barefoot over dirt or through fields increases the risk of coming into contact with hookworm larvae, which can penetrate the skin and cause infection.
