Mid-Year Examination 2011: Paper 2
Question number: 2
The life cycle of a frog (there’s a diagram. Too lazy to scan)
Ever wondered how a frog becomes a frog? Well, to start off; the adult frog can lay tens, hundreds or thousands of eggs. The mother decides to pick a place quiet, moist and humid to lay her eggs. Once the eggs are laid, they are, then, kept safe away from any hungry predetors. Some mother frogs prefer laying their eggs in water so when they hatch, there will not be any absence of newborns.
The eggs are protected by a transparent, thick jelly around the offsprings. This is to protect the undeveloped newborns from any harm. After a few weeks, the offsprings will hatch into tadpoles. Tadpoles have no hands or feet whatsoever but they do have gills to breathe through, like fish but without fins nor scales. Tadpoles are small and hard to be seen in low light; you can find them in unexpected places like the drains, sewers or maybe even big puddles. At this stage, the mother leaves her tadpoles. They do not resemble the features of their parents yet.
Soon, the tadpoles will start to grow their legs and start to swim. They still breathe using their gills and live in water. A few more weeks later the young frog will start to grow bigger in size. It will also start breathing through its lungs. That means the young frog has to go on land and continue on the develop into an adult frog.
Finally, the last stage of a frog’s life cycle. They will have long legs, hind and front. It can breathe through its lungs and live on land or in water. It has moist and thick skin. Its habitat is in either the tropical rainforests, swamps, drains or grassland. Some people like to keep frogs as pets.
