Vortex Worm (3D Structural Diagram)

Vortex worms are flatworms belonging to the family Trichomycteridae in the order Trichomycteria. The body of the vortex worm is soft and flat, symmetrical on both sides, and divided into dorsal, ventral, and anterior posterior parts; The back is slightly convex, mostly black brown in color, the ventral color is light, the front end is triangular, with one ear protrusion on each side, two black eye points on the back of the head, and no anus; The ventral surface of the body is densely covered with cilia, and the movement of cilia and muscles can enable rotifers to swim and crawl on objects. It is named after its vortex like motion when it swings.

Polarity of Water (Microscopic 3D Schematic)

Polarity of Water (Microscopic 3D Schematic)

Water is a polar compound, and due to the strong electronegativity of oxygen atoms, electron pairs tend to lean towards the oxygen side, resulting in the accumulation of negative charges around oxygen atoms and positive charges around hydrogen atoms.
