In gereral, the more poorly differentiated (the fewer complex structures that have specific functions) an organism is, the greater its ability to live and re-grow after being cut apart. Worms have this ability to re-grow in entirety, as do lower organisms like amoebas and fungi. In flatworms, their cells have the ability to differentiate into any type of tissue that the worm might need. These types of cells are called stem cells, and are the subject of ongoing research in medicine as to their applications in humans. There is a limit, however. a tiny slice of flatworm would not be able to develop into another worm.
each piece would become a new flatworm - it is one of the ways the flatworm reproduces
By cutting them with a cutting torch so that the receiver is in at least 3 pieces.
Cutting paper is an example of phisycal change.
Cutting a diameter four time will get you eight pieces of pie, not seven. You cannot get 7 pieces by cutting diameters only; for that you need to cut radii.

200 pieces.

Bisection.
Cut out pieces of a material from a sheet of that material. The pieces can be any shape because the die doing the cutting was custom machined to the required shape by a Tool and Die Maker.
where are the reproductive organs located in a flatworm
You use straight pins to secure the pattern pieces to the fabric before cutting. Remember to remove the pins before sewing, however.
Industries that requires the fabrication of machine pieces or the cutting and shaping of a material, such as aerospace and mining, use water jet cutting.
