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.
When you rub it, it creates some electrical forms inside that will charge it
Answer:
The correct option is C.
Explanation:
There are three modes of heat conduction, these are conduction, convection and radiation. Heat transfer by conduction usually involves the movement of heat through solid substances. For instance, in the scenario given in this question, the warm surface is the solid substance through which heat is passed to the insects' bodies. Thus, conduction requires direct contact.
Heat transfer by convection method usually involves the movement of heat through liquids or gases while radiation can occur in vacuum.
Mutualism is relationship that is beneficial to both organisms involved. The relationship between a plant and a bacterium called a mutualism because both of them help each other. Bacteria are involved in increasing the fertility of the soil by fixing atmospheric nitrogen and thus provide plant with nitrogen. In return, the bacteria make their homes in what usually become nitrogen "nodules" along plant roots. The plant gets food, the bacteria gets shelter, everybody wins.
C. A buildup of lactic acid in the tissues.
