Comparative anatomists study the body structures of living organisms and extinct organisms to find evolutionary links. Explain how scientists use the arrangement of fossils in rock strata, comparative anatomy, and the geological time scale to create a phylogeny chart, like the one in the elephant example above.

They use the arrangement in rock strata and examine it to find details that provide their answer.

Explanation: I'm not sure if this is right or not but i tried.  I hope you have a wonderful day!!

when scientists find fossils in a rock layer, then can use relative dating, absolute dating, or both approaches to find how old the fossils are. With this information, they can determine where these fossils fit on the geological time scale. Knowing the chronological order can help comparative anatomists identify the similarities and differences between extinct species and modern species to build an evolutionary lineage.

Explanation:

this is the exact sample answer so I would say this in your own words.

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.
