Because we are made of molecules
Answer: Evolution
Explanation: The birds where able to adapt to their new environment by developing beaks that could help them in feeding easily on their various food sources. The change may not have occured at once, but through a gradual process of evolution and inheritance. Gradually the beak changes as they try to get used to the various feeding methods in their respective environments.
enzymes are proteins that speeds up the rate of chemical reaction in a living organism . An enzyme acts as catalyst for specific chemical reaction, converting a specific sets of reactants called substrates into specific products with out enzymes life would not be exist
Explanation:
Enzymes are identified to catalyze more than 5,000 biochemical reaction types. Most enzymes are proteins, although a few are catalytic RNA molecules. Enzymes' specificity appears in their unusual three-dimensional structures. Like all enzymes, enzymes improve the reaction rate by decreasing its activation potential.
