Because epithelial tissue is capable of regeneration.
The skin consists of two tissues: the outermost, the epidermis, resting on a vascularized connective tissue, the dermis. In the epidermis, which includes several layers of cells, the outer layer is formed of dead cells that are desquamating and are constantly being replaced by proliferating basal cell cells. So, under normal physiological conditions, the epidermis, like all the epithelia, is in constant renewal. On the other hand, when accidentally, the upper parts of the epidermis are damaged as a result, for example, of a burn or a slight abrasion, the destroyed portion is regenerated thanks to an accelerated proliferation of basal epidermal cells.
Answer: The correct answer is as follows:
Stage 1) Egg - Frogs begin their life as fertilized eggs. A typical female frog can lay thousands of eggs, depending on the species. In the pond, the eggs float on the water in clusters until they hatch in 2-3 weeks.
Stage 2) Larva (tadpole) - During the tadpole stage, the frogs eat, grow and develop into froglets (with four legs) through a process called metamorphosis. As tadpoles, they rely on rudimentary gills, mouths, and tails for swimming. The tadpole's diet includes other frog eggs, bugs, mosquito larvae, and other dead insects. As their four legs and external respiration develops, the froglet is almost ready to leave the water.
Stage 3) Adult - At around 12 weeks of age, the frog has reached maturity as an adult and is ready to explore dry land. With its gills and tail totally absorbed back into the body, the frog remains an amphibian but spends most of its time out of the water. As an adult, the frog uses its sticky tongue to capture and eat insects, snails, slugs, and worms. They return to the water to lay new eggs and the cycle of life repeats.
