Mollusks are defined as Bivalves. They are called Bivalves because they have two shells. Cnidarians such as Jelly Fish do not have shells which define a bivalve (mollusks).
They have different side chains.
prokaryotic DNA is in a ring form
The annelid digestive tract is a complete system with a distinct mouth and anus, allowing for a one-way flow of food, which enhances digestion and nutrient absorption. In contrast, cnidarians, such as jellyfish and sea anemones, have a simple gastrovascular cavity that serves both digestive and circulatory functions, with only one opening. Flatworms also possess a gastrovascular cavity but lack specialized sections for digestion, making their system less efficient than that of annelids. This structural complexity in annelids allows for more advanced digestive processes.
One way in which a molecule of hydrogen and a molecule of oxygen differ is in their chemical formula. A molecule of hydrogen consists of two hydrogen atoms (H2), whereas a molecule of oxygen consists of two oxygen atoms (O2).
Organisation. Bacteria have cellular level of organisation and humans have organ system level of organisation.
2 way digestion
Sponges and cnidarians commonly reproduce asexually by budding
one way elephants from the forest differ from savanna elephants is that they are a smaller species of elephant
mollusks are slow-moving in the way that they are soft-bodied animals and protected by shells.

Mollusks and segmented worms have a one-way digestive system, a separate mouth and anus, and their larvae are very similar. This is the best evidence that they have a common ancestor.
Xylem is a one way flow
One way Mercury and Venus are the same in which they differ from other planets is that they are both very hot and dry in the daytime

All cnidarians belong to the taxonomic domain of Eukarya, which are characterised by having cells with nuclei. Eukarya covers all organisms in the Kingdom Animalia, as well as the Kingdoms Plantae, Fungi and Protista.
If they differ the same way a french one does, then the Q and A are swithched, the Z and E are switched, and the ; and M are switched.
