The wriggling movement of roundworms is a result of the fact that they do not have circular muscles, however, they do have lengthwise muscles. Roundworms are also known as nematodes.
Wriggling movement is a type of squirming or twisting motion typically seen in animals like snakes or worms. It involves a series of twisting and turning actions that allow the organism to move in a sinusoidal pattern. Wriggling can be an efficient way of navigating through narrow spaces or soft substrates.
Solids in and of themselves do move slightly, but "wriggling" is not really a form of movement one would expect to see at the molecular level.
Squirmles move by wriggling and squirming their flexible bodies. This movement is generated by the muscles along their body, allowing them to navigate through the environment and burrow into small spaces.

"They (roundworms) lack circular muscles but have lengthwise muscles. As one muscle contracts, another muscle relaxes. This alternating contraction and relaxation of muscles causes roundworms to move in a thrashing fashion." Found in the Glencoe McGraw Hill "Biology: Dinamics of Life" textbook, pg. 711
A characteristic of glacial movement is movement depends on the balance between accumulation and wastage.
Mollusks possess several features that contribute to their complexity compared to roundworms, flatworms, and corals. They have a well-developed coelom, a muscular foot for movement, and often possess a mantle that secretes a shell. Additionally, mollusks typically have a more intricate nervous system, including a centralized brain and specialized sensory organs, as well as a complex digestive system with a radula for feeding. These characteristics enable greater adaptability and ecological diversity among mollusks.
Roundworms, or nematodes, possess a pseudocoelom, which is a body cavity that is not completely lined by mesoderm. This pseudocoelom serves as a hydrostatic skeleton, providing structural support and facilitating movement through the contraction of muscles. Unlike true coeloms found in other organisms, the pseudocoelom is located between the body wall and the digestive tract, allowing for the efficient transport of nutrients and waste. Overall, the pseudocoelom is integral to the roundworm's physiology and movement.
How do these characteristics change the movement of air?
Data that includes both unit cargo and personnel characteristics
movement,energy and drama
i was asked the same question but all u have to do is go to wikipedia and find the characteristics :)
