Babies with very low or very high birth weight are less likely to survive. observe a graph of the data. a graph entitled percentage of babies born at different weights has weight in pounds on the horizontal axis, and percentage on the vertical axis. a small percentage of babies are born at the low and higher birth weights, and a greater amount are around 7 to 8 pounds. which statement is a valid claim that could be made using the data in the graph? directional selection is occurring because the graph favors an extreme. stabilizing selection is occurring because the average is favored. disruptive selection is occurring because the two extremes are favored. biodiversity selection is occurring because of the greater variation.

"-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."    

is this for the e2020 class

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!
