Frogs lay their eggs in water or wet places. A floating clump of eggs is called frog spawn. ... This quickly becomes a tadpole, a baby frog. The tadpoles grow until they are big enough to break free into the water. This can take from 3 days to 3 weeks, depending on what kind of frog they will become. They eat very small...

The process of metamorphosis from tadpole to frog. ... As metamorphosis progresses, it is vitally important that the developing frog can easily get out of the water. Partially submerged sticks, wood and rocks can be used to make ramps out of the water (make sure they are stable), and it is a good idea to make a gravel slope...

We have proposed a dual function model for TR during development based on studies of frog metamorphosis. Here we examined an important assumption of this dual function model by using the chromatin immunoprecipitation assay, namely constitutive TR binding to promoters in vivo.
