Scientists performed many experiments on the Challenger. These experiments did not include
deep sea trawling .
bottom sampling.
water analysis.
sonar soundings.

After the collapse of its fuel tank, the Challenger itself remained momentarily intact, and actually continued moving upwards.

im guess thats wht ur asking i cant really understand ur question

The shuttle program resumed flights in 1988. After the Challenger wreckage was examined, most of the pieces were buried and sealed in abandoned Minuteman missile silos at Cape Canaveral Air Force Station, where they remain today. Challenger's explosion changed the space shuttle program in several ways.

thats more like it ig im not sure

this is math not biology xd

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."
