Inner lining of urinary bladder is covered with transitional epithelial tissue, which provides protection to the tissues beneath this layer from alkaline or acidic urine.
Along with protection, epithelial tissue also has ability to stretch significantly. This property of epithelial tissue helps the bladder to accommodate large amount of urine.

Explanation:
Almost all coal that is used today has its origins in the Carboniferous period. The Carboniferous period was a warm and wet one, with the majority of the land being swampy and covered with dense rainforests of ancient tree species. By the end of this period, the climate quickly changed, resulting int he collapse of the rainforests. As the trees were dying out, they were falling in the swamps, quickly being covered by the mud, so remaining largely preserved. Over time they got exposed to higher pressure and temperatures as they were getting deeper into the crust, eventually resulting in the formation of the coal.

Antibiotics work by breaking down the cell walls of bacteria or interfering with the bacteria's ability to repair its cell's DNA, according to How Stuff Works
