The resting potential is mostly determined by the concentrations of the ions in the fluids on both sides of the cell membrane and the ion transport proteins that are in the cell membrane.he resting potential is mostly determined by the concentrations of the ions in the fluids on both sides of the cell membrane and the ion transport proteins that are in the cell membrane.
Usually when a worm is cut in two, the longer piece regenerates, especially if it has only the tail to regrow).

The ovaries are situated. near to the mid-line of the worm and their narrower free ends float almost horizontally in the coelomic. fluid.
Worms have a very interesting method of reproduction. There are no male and female worms â all worms are the same and each produce both sperm cells and egg cells. When a worm is mature and ready to reproduce, it finds a partner worm.

The sperm cells are exchanged by the worms through this mucous.
