Question

propose a hypothesis to account for the data related to the cell life spans of the lining of the esophagus,small intestine, and large intestine.

Answer 1

 Epithelial cells that need to absorb water from undigested food matter lives longer than those which are exposed to mixture of gases constantly,as compared to those which take active part in digested food absorbment,whose life is the shortest.

Answer 2

Answer:

There are different types of cells in the human body and based on the type of cells there are different life spans of different types of cells.

The cells of the lining of the esophagus has a life span of 2 or 3 days after which they die and in place of the older cells the new cells are formed.

The cells that are found in the lining of small intestine has a lifespan of 1 or 2 days after which new cells are generated.
