Answer:

Option D,  a research paper published in an academic journal and an approved PhD dissertation

Explanation:

Nicholas must present her discovery with back up of strong literature review. This literature review must include papers published in good journals and only approved research dissertation.  

An internet blog, news article and college level textbook are not considered as an approved study. These are not reviewed or approved by any peer group or associations.  

Good papers of any good journals are reviewed and examined thoroughly by the peers and thus they can be used as a backup of any study.  

Hence, option D is correct

Andrei [34K]

Answer:

The correct answer is option d. "a and b".

Explanation:

Plenty of methods had been developed to estimate the body size of dinosaurs such as the gigantic Sauropods. One of the first estimations that paleontologists used was the  Archimedes principle, consisting in dunking the entire skeleton of a Sauropod into a pool of water and measure the water displacement or more precisely small dinosaur models. However this method requires the preservation of almost the entire skeleton. A more used and useful method is to measure the length of the legs from the hip to the foot and using a 2/3's power relationship convert that to a mass. This method is more used since it only requires a couple of leg bones, which are often well preserved.
