Well if you did mean "eat" and not "watch" the answer would be.....Cellulose is a carbohydrate which is present in the plant cells. The cellulose is a polymer with glucose as the monomer units. The monomer units of cellulose is attached by the beta linkages. The cellulose provides structural support to the plant cells by forming micro-tubules. The humans cannot eat the diet rich in cellulose because they lack the enzymes that are needed to digest them. Some animals, such as cows and termites have these enzymes but not the humans. So the answer would be "people cannot digest cellulose".
Answer;
-Thoracic
Thoracic because of the rib facet on the body and elongated spinous process
Explanation;
-Thoracic Vertebrae functions to hold the rib cage and protect the heart and lungs. The twelve thoracic vertebrae are numbered T1 to T12. The range of motion in the thoracic spine is limited.
-Distinguishing features of the thoracic vertebrae include; the presence of facets on the sides of the bodies for articulation with the heads of the ribs, and facets on the transverse processes of all, except the 11th and 12th vertebrae, for articulation with the tubercles of the ribs.
