Answer:columnar describes cell shape.
Simple describe the number of layers
Explanation: epithelial tissues are one of the four major tissues of the body.the others being nervous, muscular, connective tissues.
Epithelial tissues are made up of thin cells that cover the external and internal surface of the body.
The cells may form one layer or more and they occur in several shapes.if they form one layer ,it is called simple.if they form several layers,it is called stratified.
Some are called pseudo-stratified because the cells occur with varying lengths and give the impression of stratified but they are actually made up of one layer.
Simple columnar epithelium is a single layer of tall, closely packed cells. They possess cellular extensions ,such as microvilli in the small intestine, or the cilia in the female reproductive tract.
The answer is Glycogenolysis
When we are hungry or skipped a meal our glucagon, <span>an hormones</span> that regulates blood-sugar levels, is released to avoid glucose levels in the blood to decrease to a risky value.
Glucagon makes the liver, but also the muscle, to breakdown accumulated glucose called glycogen into glucose to increase blood-sugar levels. This process is called Glycogenolysis and can also be stimulated by an increase in epinephrine during fight-or-flight responses.
