The correct answer will be
B. false
Systematic error affects the
measurement in a constant way and represents stable factors that affect the
observed score in the same way each time the measurement is made. Systematic
error is a steady, repeatable error joined with faulty measuring equipment or an
imperfect experiment design.
A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.
