Over the years, a Mexican wolf population in an area of Arizona became severely depleted. The U. S. Fish and Wildlife Service put in place a program to breed wolves and release them into the wild. A survey of the Mexican wolf population since the program’s introduction in 1998 is shown (see the picture). The expansion of the Mexican wolf population in Arizona raises the possibility of the formation of a hybrid zone with coyotes along the boundaries of their range. Which statement, if true, would most likely result in the formation of a stable hybrid zone?

A. Coyote-wolf hybrids are less fit in the hybrid zone than either parental species.

B. Coyote-wolf hybrids are more fit in the hybrid zone than either parental species.

C. Coyote-wolf hybrids are less fit outside the hybrid zone than either parental species.

D. Coyote-wolf hybrids are more fit outside the hybrid zone than either parental species.

the index of refraction of the second medium is higher. i just took the test trust me !

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."
