The doctor finally figures out what is wrong with you and prescribes a medicine that will return you to full health. the order is for 25 mg of the medicine. the nurse walks in with a liquid and you ask to see the bottle. the bottle says 100 mg of medicine per 15 ml of liquid. how many milliliters should she give you? would she need to bring that to you in a dropper, a little cup, a glass, or a large bottle?

The drug solution has a concentration of 100 mg/15 mL and the needed dose is 25 mg. There should be computation of the required volume. The computation is as follows:

Volume = (25 mg)/(100 mg/15 mL)

Volume = (25 mg)/(6.67 mg/mL)

Volume = 3.75 mL

The patient needs to take 3.75 mL of the drug with a concentration of 100 mg/15 mL to get a dose of 25 mg. A measuring cup (or a little cup) may be used as these measuring cups are calibrated to match volume dosages.

"-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."    

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs
