Explanation:

Living organisms are characterized by certain processes they undergo. These processes makes them defined as living. Mollusks are a group of invertebrate animals that are often protected by hard shells. They undergo characteristics of living things like respiration (gaseous exchange), excretion (pass out waste substances) and even the circulation of fluid within their body system but they do not perspire.

In other words, animals of the mollusk group do not sweat or exude water from their skin because they do not possess sweat glands considering the fact that they are cold-blooded animals and externally regulate their temperature.
