Blood flowing through lung tissue absorbs oxygen from the lungs and releases carbon dioxide to the lungs. Which explanation describes how this exchange occurs? :Blood flowing to the lungs contains a higher concentration of carbon dioxide and a lower concentration of oxygen than the air in the lungs.
:Blood flowing to the lungs contains a lower concentration of carbon dioxide and a lower concentration of oxygen than the air in the lungs,
• Blood flowing to the lungs contains a lower concentration of carbon dioxide and a higher concentration of oxygen than the air in the lungs.

The movement of tectonic plates in two different locations is shown below: two blocks labeled location a and location b are shown. at location a the top layer of the block shows two horizontal arrows pointing towards each other. small dunes are shown in the middle between the two arrows. the block labeled b has a vertical line in the middle. on the left of the line there is an arrow pointing down. on the right of the vertical line there is an arrow pointing up which statement is most likely true? subduction may occur in both locations. earthquakes may occur in both locations. subduction may occur in location a only and a volcanic eruption may occur in location b only. an earthquake may occur in location a only and a volcanic eruption may occur in location b only.

How did the miller-urey experiment impact the way scientists think about the origins of life? use what you know about the miller-urey experiments to discuss the factors needed for life to arise, and speculate on whether life could arise on another planet.
