You observe a tissue under a microscope. there appears to be a lumen on one side of the tissue. lining this lumen, the cells seem to have long, fingerlike projections. beneath the projections, the cells seem to have the shape of shoeboxes and are packed tightly together. what type of tissue are you looking at? you observe a tissue under a microscope. there appears to be a lumen on one side of the tissue. lining this lumen, the cells seem to have long, fingerlike projections. beneath the projections, the cells seem to have the shape of shoeboxes and are packed tightly together. what type of tissue are you looking at? transitional epithelia stratified squamous epithelia simple cuboidal epithelia simple columnar epithelia

You are looking at a simple columnar epithelial tissue.

Explanation:

Epithelium morphology correlates with their function. Those who intervene in secretion or absorption processes are simple epitheliums. Cells high frequently reflect their secretory or absorptive activity degree. Epitheliums that transport substances are characterized for presenting cubic or columnar cells.

Simple columnar epithelia is a single layered columnar epithelium formed by cells that are taller than wider, getting a shoebox shape. These cells might present fingerlike projections in their apical surface, lining the lumen. These modifications are known as microvilli.

The columnar epithelium lines the interior surface of hollow or tubular organs such as the digestive tract and the uterus.

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
