Enzymes are protein catalysts. What is the role of a catalyst?
1 answer:
Enzymes are proteins catalysts and speed up reactions by lowering the energy needed to start them. Catalysts speed up the reactions in the cells so that they can happen in a fraction of a second, making them happen more quickly. Without catalysts, most cell reactions would not happen even over long periods of time.

<u>Answer </u>: C) 10%.
<u>Explanation </u>:
The cow will get only 10% energy from the hay as the transfer of energy from a lower to a higher trophic level follows the ten percent law. According to the ten percent law of energy transfer, only 10 percent of the total energy gets transferred to the next trophic level in a food chain. For example, if the hay had 100 joules of energy, the cow will get only 10% of 100 J i.e 10 J energy. The reason why only ten percent energy is transferred is because the rest is lost in the form of heat in the atmosphere.
