• after frida stops exercising, she continues to breathe heavily. what is most likely occurring in her body? heavy breathing during exercise has produced an oxygen surplus in her muscles. this oxygen is being transported to her lungs. this is a result of aerobic respiration. heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. lactate is being transported to her liver. this is a result of aerobic respiration. strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration. strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration.

• on a coordinate plane, 2 lines with negative slopes are shown. line m n goes through points (negative 2, 0) and (negative 6, 8). line m prime n prime goes through (6, negative 4) and (2, 4).use the graph of the lines to determine if the two lines are parallel. line mn was translated down units and right units to create line m'n'. the slope of line m n .the slope of line m prime n prime .
