Peppered moths vary in color from light gray to almost black. the color of any moth depends on how many black spots are found on its wings. the name "peppered" refers to these black spots. during the day, the moths rest on trees. in england where the moths live, many light gray trees were covered with soot that came from the smoke stacks of factories. the trees got darker and darker from the soot. over time the peppered moth population in polluted areas a) will become extinct. b) will become darker in color. c) will probably stay the same. d) will become lighter in color.

The correct answer is B) Will become darker in color

Explanation:

According to the evolution theory and the natural selection model, organisms adapt to changes in the environment and evolve as features that make them more suitable to survive and reproduce prevail over time. This implies, in the case presented peppered moths that are darker will be more likely to survive and reproduce because they can camouflage in the dark trees. This will cause over time, most of the peppered moths are darker (Option B) as this feature represents an advantage in terms of survival and reproduction. Similarly, if trees are no longer covered with soot the peppered moth population will evolve to fit in new conditions.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
