Answer:
atrial systole, ventricular systole, and complete cardiac diastole.
Explanation:
Every single beat of the heart involves three major stages: cardiac diastole, when chambers are relaxed and filling passively; atrial systole when the atria contract leading to ventricular filling; and ventricular systole when blood is ejected into both the pulmonary artery and aorta

Answer:
The correct answer is C Speed or velocity of the reaction
Explanation:
Enzymes are homogenous,biological catalyst that is used to speed up the reaction.
Enzyme do this by decreasing the energy barrier also called activation energy of the reactants but do not hamper the reaction equilibrium.
The enzyme itself remain unchanged throughout the overall reaction.
You can have error both human error i.e eye balling a measurement to what looks close. and then you have inherent error the error that is already in the equipment i.e a 2 scales one can give a measurement of x when set to zero and if put it on a second scale you could get a measurement of y when set to zero because of calibration gravity etc things you cant control
