Explanation:
Radon is a naturally occurring gas, which is produced due to the radioactive decay of the Radium element. It is one of the dense gas that is mostly concentrated in the lower portion of the houses, and are trapped in the cracks and fractures of the walls of houses and buildings.

<span> Many cells have specialized shapes that help accomplish the task of absorbing, excreting large amounts of materials.

Instead of being a large round blob, it is long and stretched out to have a large surface area where absorption and excretion can occur. I hope this helps.</span>
