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.
<span>A fossil leaf that is made only of carbon preserved between two rock layers is called carbon film fossil.
</span>Characteristic of the carbon film fossils is that they are primarily composed of carbon. The fossil leaf has usually lost <span>internal components (cell walls and internal cell structures ).</span>
your answer would be: <span>Webbed toes help frogs move around better in water. They also have semi-permeable skin that allows them to </span>absorb<span> the water (since they do not drink) and their bodies dehydrate if they are not in water for long amounts of time.</span>
The development of a community where no life has existed before is called primary succession.
Hope this helped ! (:
