The graph below plots the temperature and luminosity of stars on the main sequence. Four locations (A, B, C and D) are graphed on a curve representing luminosity vs temperature. The curve begins are high luminosity and high temperature decreasing in luminosity and temperature as it approaches the right side of the curve. From left to right are points representing Location A, Location B, Location C and Location D.

At what location is the star with the greatest initial mass most likely to be found?
Location A
Location B
Location C
Location D

heat a spark and oxygen

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.

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.

a. 35°c

b. 25°c

c. 10°c

d. 40°c
