Enzymes lower the activation energy by forming a complex with substrate (enzyme-substrate complex). There are a few mechanisms of enzymes activity:
• Enzymes can change the charge distribution of the molecule
• Enzymes can change the substrate bonds
• Enzymes can reduce the reaction entropy.
All of the mechanisms tend to bring the molecule (reactant) to unstable state called the transition state (high-energy state).
Body fossils include bones, teeth, claws and skin. Therefore the answer would be A, imprints.
Third, first, second (i guess, i didnt do physics for a year)
Answer:
Explanation:
Two offspring cells with the same genetic material as the parent cell. Two offspring cells with half genetic material as the parent cell
