Answer these questions based on what you learned from the lesson. are single-celled organisms with no nucleus. the kingdom is relatively small. eubacteria are classified by . coccus are round bacterial cells. bacillus are rod-shaped bacterial cells. spirillium are spiral-shaped bacterial cells.

1.) [Bacteria] are single-celled organisms with no nucleus.  

2.) The kingdom [Archaebacteria] is relatively small.

3.) Eubacteria are classified by [shape].

4.) [coccus] are round bacterial cells.

5.) [bacilli] are rod-shaped bacterial cells.    

6.) [spirilli] are spiral-shaped bacterial cells.

i believe the correct answer is d

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."
