Jaden listed the similarities of using coal, natural gas, and petroleum to generate electricity.

Coal, natural gas, and petroleum:
– use turbines
– require heat
– convert electrical energy to kinetic energy
– produce pollution in the form of smoke

Which best describes Jaden’s mistake?

Only coal-fired power plants use turbines.
Power plants do not require heat.
Kinetic energy is converted to electrical energy.
Coal does not produce pollution.

Which best explains why viruses do not have special structures or enzymes that allow them to make their own food? viruses can use energy in living cells that they infect. viruses can replicate inside a host that they infect. viruses can cause contagious illnesses in host cells. viruses integrate their rna or dna into infected cells.

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
