The activation energy needed for the chemical reaction decreased by an Enzyme.
Activation energy is the amount of energy required in a chemical reaction.
Enzymes lowers the activation energy by increasing the rate of reaction.
The energy required for a reaction to start is called activation energy. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.
<span>The quality of Australian land is unique as the properties of the earth crust are different. There is no much of evolution of land and is an isolated space which is the reason for the said placental mammals do not habitat there but has their own diverse kind of these marsupials.</span>
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
