Why does the left ventricle have a thicker wall than the right ventricle? a. a more muscular wall is required to supply the pumping that powers the flow of blood into the systemic circuit b. the left ventricle is responsible for systole while the right ventricle is responsible for diastole c. the position of the heart in the chest cavity allows for the left ventricle to develop a thicker wall than the right ventricle d. a more muscular wall is required to supply the pumping that powers the flow of blood into the pulmonary circuit e. the left ventricle contains the pacemaker?

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
