Do mollusk cells have a nucleus?

What feature is found in all mollusks bilateral symmetry radial symmetry a hinged shell or the ability to swim?
All mollusks exhibit bilateral symmetry, meaning their body can be divided into two mirror-image halves along one plane. While some mollusks, such as bivalves, have hinged shells, this trait is not universal among all mollusks. Radial symmetry and the ability to swim are also not characteristics found in all mollusks. Thus, bilateral symmetry is the defining feature present in all members of this diverse phylum.

Which features of the squid are common to all of th mollosks phylum?
Some common features of squids and other mollusks include a soft body with a muscular foot, a mantle that secretes a shell (if present), and a radula for feeding. They also have a visceral mass containing organs such as the heart, digestive system, and reproductive organs. Additionally, mollusks possess a mantle cavity that houses the gills and functions in respiration. However, not all mollusks have all these features, as there is a wide diversity within the phylum.
Why two structures are missing in bivalves but are present in all other mollusks?
Bivalves lack certain structures, such as a radula and tentacles, which are present in other mollusks due to their unique feeding and lifestyle adaptations. Bivalves primarily filter-feed by siphoning water through their shells, making the radula unnecessary for scraping food. Additionally, their body plan has evolved to prioritize a two-part shell and a sedentary lifestyle, resulting in the loss of structures that are more suited for active predation or grazing seen in other mollusk classes.
What is the function of the visceral mass in mollusks?
Visceral mass of mollusks contain all organs but head foot and gills . Thus vascular , excretory reproductive , part of nervous and digestive functions function are performed by visceral mass .
