Recent work in classification of life on Earth has shown that what were once called prokaryotes are much more diverse than ever suspected. The prokaryotae are now divided into two domains, the Eubacteria and the Archaeabacteria, as different from each
other as either is from the Eukaryota. One organism, the blue-green algae or cyanobacteria, has left a fossil record that dates back
nearly 3.5 billion years and is among the oldest fossils known. A few hundred years ago, this organism was classified as a plant,
then more recently as a protist. Today it is classified in the kingdom Eubacteria. Which of these would NOT be evidence that
scientists compiled to place cyanobacteria in the Eubacteria.
A)
presence of cell walls containing peptidoglycans
B)
presence of chloroplasts for photosynthesis
C)
contains a nucleoid rather than a nucleus
Eliminate
D)
forms an outer capsule with slime coat

"-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."
