While many non-avian dinosaurs achieved gigantic sizes, the sauropods were the true giants of the mesozoic. in fact, the largest terrestrial vertebrates to ever live are members of this clade. however, it is not easy to estimate how large an animal was from just a fossil skeleton. which of these is a method by which dinosaur body size is estimated?
a. paleontologists 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
b. paleontologists use archimedes principle and dunk the entire skeleton of a sauropod into a pool of water and measure the water displacement
c. paleontologists make scaie models with estimates of muscle mass, density and skin morphology and then estimate the volume of the model and scale it up
d. a and b
e. a and c

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.

the answer is tropical areas. the tropical areas obtain more

radiant energy from the sun than they lose to space through terrestrial

radiation, and vice versa for polar areas. earth has an energy remaining in the

tropics and an energy scarcity for the polar areas.

explanation:

mientras se trata la anorexia o la bulimia, es importante buscar ayuda antes que nada. un profesional de la salud mental será el más útil para aquellos que sufren anorexia o bulimia. este es un buen lugar para comenzar, sin embargo, ver a otros profesionales como dietistas registrados, especialistas médicos y dentistas podría ayudar a alguien a recuperarse de un trastorno alimentario. después de la ayuda profesional, o si la ayuda profesional no es una opción, alguien que se recupere de la anorexia o la bulimia debe rodearse de compañeros de apoyo, padres u otros miembros de la familia que también estén comprometidos con el proceso de recuperación.

hope this you! : )
