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.

Agata [3.3K]
To answer this question, let us first mention what is food danger zone. Well, this refers to the temperature range in which bacteria grows faster in the food. The range is defined as 30 to 140 degree Fahrenheit or can be converted into 4 to 60 degree Celsius. Going back to the question, the maximum number of hours that a food can be held in the food danger zone is only 2 hours. Beyond this 2  hours, the food is not safe to be eaten and the person who dares to eat this food might get some illness and worst might experienced food poisoning.
