Which explains why atoms become more stable when they form bonds? the atoms lose negative charges, which brings the atoms’ energies up. the electrons in the bonds fill the atoms’ outer energy levels. the electrons in the bonds slow down, which brings the bond energy down. the electrons are shared, which makes the atoms bigger.

Match the following terms describing electrical events with the correct phases of the cardiac cycle. the ventricular muscle cells depolarize at the start of this phase. during this phase, na+ entry through the funny channels causes the pacemaker potential of sa nodal cells to gradually become less negative until it reaches threshold. the ventricular muscle cells repolarize right before this phase. the cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. a. isovolumetric relaxation b. ventricular ejection c. isovolumetric contraction d. ventricular filling
