A snail’s shell grows through the secretion of calcium carbonate by the mantle. As the snail increases in size, the mantle continuously adds new layers to the shell, making it larger.

Non-living things cannot show genuine responses to stimuli. Any apparent response is due to mechanical or chemical processes rather than biological reactions, as non-living entities lack the complexity of living systems.
A snail’s shell helps maintain homeostasis by preventing excessive water loss and protecting the snail from environmental changes. It aids in regulating the internal moisture levels essential for the snail’s survival.
Key characteristics indicating a creature is alive include growth, reproduction, responsiveness to stimuli, and the ability to maintain internal stability. These traits are essential for distinguishing living creatures from non-living things.
No, a shell alone cannot be considered a living part of a snail. The shell is a non-living structure produced by the living snail and serves as protection and support.
Living creatures maintain homeostasis by regulating internal conditions such as temperature, pH, and hydration. They use feedback mechanisms to adjust their internal environment, ensuring stable conditions despite external changes.
