Answer:
The correct answer is: Epithelial tissue, <u>because 1) it's in direct contact with the environment, and 2) their cells are rapidly dividing. The two factors contribute greatly to the appearance of cancer.</u>
Explanation:
Epithelial tissue is one of the four basic tissue types (along with connective tissue, muscle tissue, and nervous tissue), and it is characterized for being <u>avascular</u> (there are no blood vessels in it), being <u>very cellular</u> (it has many cells and not many fibers), <u>having polarity</u>, being capable of <u>regeneration,</u> and being <u>attached to a basal membrane</u>.
The main function of the epithelial tissue can vary from the location of it, since it gives each organ a function, but as a whole, we could say it is involved in <u>transport, secretion, protection, sensing, and absorption</u>.
While the epithelial tissue's characteristics (such as their rapid regeneration) are crucial for its highly important functions, this can also make them home to carcinomas and adenocarcinomas.
