Answer 1

Flatworms use a system of canals and tubes with the mouth as their excretory organ. They belong to the Phylum Platyheminthes. Flatworms can be cut in half creating two individuals by binary fission. Binary fission is a type of asexual reproduction in which the offspring has the same features and characteristics of the parent. During binary fission, the DNA replicates into two and goes at the end of each membrane. And then the cell membrane divides into two daughter cells. Then cytokinesis follow.
