Scientists use specific levels of organization to analyze the biosphere. The Everglades consist of a large area of subtropical wetlands in Florida. Various species of plants and animals can be found in the Everglades, including panthers, cypress trees, herons, and alligators. A photo of cypress trees in the Florida Everglades. A heron wades through the water in the foreground. The group of ecosystems on Earth that feature climate, vegetation, and wildlife similar to the Everglades is:. a. a biosphere. b. a community. c. a population. d. a biome.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

trachea, alveoli, lung capillaries, arteries

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project
