THIS IS ACTUALLY SCIENCE! !!According to the law of conservation of energy, which changes would decrease the total energy of a system? A. An addition of 400 J of GPE and a loss of 350 J of thermal energy B. An addition of 200 J of thermal energy and a loss of 350 J of kinetic energy C. An addition of 500 J of thermal energy and a loss of 250 J of thermal energy D. An addition of 300 J of kinetic energy and a loss of 250 J of thermal energy​

i believe the answer is c

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
