How does a Tadpole change into a Frog?
Metamorphosis of the tadpole larva into an adult frog is one of the most striking transformations in all of biology. It transforms a fish-like water breathing, herbivorous tadpole into a tetrapod, amphibious, air-breathing, carnivorous frog. […]

How Enzymes speed up the chemical reactions?
Enzymes are complex biological molecules which catalyze or greatly speeds up the rate at which a chemical reaction will occur. The key concept behind the speeding up of a chemical reaction by an enzyme is that it reduces the activation energy required for a reaction. In doing so, it speeds up the reaction. […]

Mesozoic Era – the Age of Reptiles.
The Mesozoic Era spans from about 252 million years ago to about 66 million years ago that means it began roughly around the time of the end-Permian extinction. The amphibians were declining after a long period of supremacy among the animals and the reptiles were gradually replacing them. Many of them became very large fearsome and came to dominate the animal life practically everywhere and spread into all habitats. For this reason, the Mesozoic era is also called the Age of Reptiles or the Age of Dinosaurs. […]
