Answer 1

1. epithelial cells are classified on the basis of their shape of the cells and the functions they perform.

2. columnar epithelial tissue is found in the small intestine for the absorption of nutrients.

3. Cilia on pseudostratified columnar epithelial tissue are found in the trachea walls. They help to trap the foreign material and sneeze them out.

4. Microvilli are found on the walls of the small intestines.

5. All connective tissues have all this in common: cells, protein fibers, and large amorphous ground substance.

7. The functions of adipose tissues are an insulating material, by preventing loss of heat through skin, and protective function provides mechanical support from shocks.

8. Collagen is the most abundant protein in the animal kingdom. It is found in the extracellular matrix and connective tissue.

9. Dense connective tissues form a strong and are a rope-like structure, which forms tendons and ligaments.

10. Two types of striated muscles are cardiac muscles (heart muscles), and skeletal muscles (skeletal muscle are attached to the skeleton).

11. Skeletal muscles are multinucleated, cylindrical, striated, and voluntary muscles.

12. Desmosomes connect cardiac muscles cells to each other.

13. There are three germ layers, ectoderm (outer layer), endoderm (inner layer), and mesoderm (middle layer). Muscle cells

are a form of ectoderm layers.

14.
