Answer 1

1. Transitional epithelium ( these are type of epithelial tissue which is made up of multiple layers of cells. The multiple layer provide flexibility to the tissue and allow them to stretch and expand according to the need).

2. Urinary bladder ( because urinary bladder is subjected to high pressure which cause stretching of bladder when urine fills in. Other locations of transitional epithelial tissue are ureter and ducts of prostate gland).

3. Villi( villi are present in the small intestine to increase surface area for absorption. Villi are finger like projection form the enterocytes).

4. Columnar ( the cells in the small intestine or enterocytes are of columnar shape).
