True or false. All mollusks are cemented permanently to the ground
Answer:
False
Explanation:
Mollusks are living organisms that can move around often, like mussels and clams, and oysters.
The statement "All mollusks are cemented permanently to the ground" is definitely false.
What are mollusks?Mollusks may be defined as a type of living organism that has a soft-bodied invertebrate of the phylum Mollusca, usually wholly or partly enclosed in a calcium carbonate shell secreted by a soft mantle covering the body.
According to the context of this question, mollusks also have the ability to move around their surrounding in order to facilitate their survival and interactions with other living forms. The characteristics of mollusks may include a mantle with a mantle cavity, a shell (except where lost), visceral mass, a foot, and a radula. The odontophore is in the mouth of most mollusks and it supports the radula.
Therefore, the statement "All mollusks are cemented permanently to the ground" is definitely false.
