When performing scientific investigations, scientists often use different approaches. For example, one scientist might add an extra step to his or her investigation that another scientist's investigation does not need. In other cases, certain steps might be repeated or arranged in a different order. Even with all the different ways scientists can approach a problem, there are some basic steps that usually occur in the same order. For a single scientific investigation, which of the following shows steps in the most appropriate order? hypothesis gather experimental data draw conclusions question → → →

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.
