Evolution is a change in frequencies of alleles in the gene pool of a population. This definition of evolution was developed as
a result of the work in the 20th century by Hardy and Weinberg. Through mathematical modeling based on probability, they
concluded that allele and genotype frequencies in a population will remain constant from generation to generation in the
absence of evolutionary influences. Evolution will not occur in a population if seven conditions are met:
1. mutation is not occurring
2. natural selection is not occurring
3. the population is infinitely large
4. all members of the population breed
5. mating is totally random
6. everyone produces the same number of offspring
7. there is migration in or out of the population
In northern Canada, a population of rabbits was predominantly white in color. The allele for white color is recessive (9), while the
allele for gray color is dominant (G). Over the last several decades, the average annual temperature of this area has increased, and
the long-term deposits of ice and snow have become scarce. We see the result of this change in the graph above. How would
Hardy-Weinberg explain this change in terms of allelic frequency?

The answer is (C) The dominant allele will decrease while the recessive will increase in the gene pool

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."
