Answer:
I'm pretty sure it's a comet!
Explanation:
A comet's nucleus is like a snowball made of ice. As the comet nears the Sun, the ice starts to melt off, along with particles of dust. These particles and gases make a cloud around the nucleus, called a coma. A comet's nucleus, or heart, is the solid chunk of something in the center of its fuzzy coma.
Most comets have two tails. ... Because the comet dust particles are so small, they are pushed away from the Sun into a long tail. Another tail is made of electrically charged molecules of gas (called ions). Very rarely a comet will have a third tail made of sodium, which we usually don't see with our unaided eyes.
Very sorry if this is incorrect, I hope this helps!

Simple cuboidal epithelium is a type of epithelium that consists of a single layer of cuboidal cells. These cuboidal cells have large, spherical and central nuclei. This type of tissue is found lining parts of organs and ducts in the body. its structure allows for absorption and diffusion in those areas. Mostly found in organs that are specialized for secretion, such as salivary glands ( part of the digestive tract) and thyroid follicles, and those that are specialized for diffusion, such as the kidney tubules.
