tino4ka555 [31]

Answer:

Ribosomes are the machinery of protein synthesis in the cell. They are associated with different organelle of the cell. They are also found free-floating in the cytoplasm of the cell.

The organelle which ribosomes interact are plasma membrane in prokaryotes and endoplasmic reticulum(ER) in eukaryotic cell. Ribosomes are present on the surface of the ER and helps in protein synthesis in the ER. In prokaryotes, there is no ER so it is associated with plasma membrane and perform protein synthesis.

The specialized function of ribosome is to perform protein synthesis and these proteins are necessary for cell because protein are important to make enzymes that regulate the metabolism of the cell. So if protein synthesis stops cell will not able to perform important metabolic activities to survive and it will die.

Having a large number of ribosomes benefits cells because it fastens the protein synthesis process in the cell. So large amount of protein can be produced in less time.

Hernia refers to the development of outgrowth or protrusion of all or part of the organs through their cavity walls or membrane. Diverticulosis is herniation of mucosa and submucosa of the wall of the colon. Diverticulosis is one of the conditions caused by the imbalance of homeostasis. Many sac-like outgrowths develop in the wall of the colon. The outgrowths are in the form of pouches and are called diverticula.

The out-pouching occurs where the muscularis layer of the wall of the colon has weakened. The people with diverticulosis may have no symptoms and no complications. However, when diverticulosis causes inflammation, the person experiences several complications such as pain, vomiting, nausea, etc.
