The small intestine is the site of digestion and absorption of nutrients. a single layer of epithelial cells lines the small intestine. in the duodenum (the first section of the small intestine), these epithelial cells secrete large quantities of digestive enzymes (a specialized type of protein). which of the following features would be typical of these epithelial cells? a. they contain large numbers of lysosomes. b. they have more smooth endoplasmic reticulum than rough endoplasmic reticulum. c. they contain large quantities of rough endoplasmic reticulum. d. they have larger nuclei than cells that secrete large quantities of lipids.

The corect answer is a They contain large number of Rough endoplasmic reticulum

Explanation:

The epithelial cells lining the small intestine helps in both digestion nd absoption of nutrients.The epithelial cells do the same by secreting large amount digestive enzymes.

         The digestive enzymes are proteins that are produced by rough endoplasmic reticulum, sorted into golgi appratus and then packed into the vesicles.

     Small intestine secrete various digestive enzymes as well as bicarbonate that help in the digestion and absorption of nutrients.

a. population growth is decreasing

-2

+4

-10

-3

-8

-3

so the population decreased by 24 because 3+3+8+10+2=26-2=24.
