A tympanic membrane, (is also called a tympanum), is the circular patch of skin directly behind the frog’s eye that we commonly call an eardrum. It functions much like our’s does.
The tympanum sends sound waves to the middle of the war then to inner ear, which allows a frog to hear both in the air and below water.
Frogs have only one opening, called the cloaca, through which both feces and urine pass. Humans, however, possess two separate orifices for urine and feces to exit through.
They are also describe as a plant with naked seeds because during pollination ovule is not enclosed by the carpel except some kind of scales during development .....In contrast the angiosperm have evolved flower hence they are also called flowering plants
