Which observations show that a change in state of matter has occurred? wood burns, producing gas and an ashy residue. overnight, dew forms on the grass. an alkali indicator changes color when added to a cleaner. vinegar has a strong smell

When dew forms, it’s a change in a state of matter from water vapor to liquid. When vinegar evaporates, it also represents a change in state. The reason we can smell vinegar in a bottle is because it’s evaporating.

So the answers are

B: Overnight, dew forms on the grass.

D: Vinegar has a strong smell

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."    

yes it is weird but true
