Based on fossil evidence, scientists concluded that whales evolved from hoofed mammalian ancestors that lived on land. New evidence confirms this and suggests that among the hoofed mammals, the hippopotamus is the closest living relative of whales. Which of the following was the most likely source of this new evidence? A. Comparisons of lifespans B. Comparisons of gene sequences C. Mapping of geographic distributions D. Calculation of population birth rates

b.

the accuracy of the data.

the dissolution of polymer can be thermodynamically described in 2 steps.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
