In order to provide nutritional information about food, scientists must evaluate how many calories a given food has per serving Given what you know about chemical and thermal energy, which is the best procedure for a scientist to use to determine how many calories are in a certain food? A Burn the food and determine the change in temperature from the beginning to the end.

B Dissolve the food in water and determine how it changes the boiling point of the water.

C Burn the food and determine how much it raises the temperature of a known amount of water.

D. Dissolve the food in water and determine if it changes the standing temperature of the water.

(me out over the last several centuries, scientists have made the following broad observations while investigating several branches of the life sciences: -the fossil record shows that different types of organisms have existed at different times in earth's history. -many organisms have similar body structures that seem to be adapted to different ways of living in their environment. -organisms of different species often share similarities in stages of embryonic development. -many species share genetic similarities, and almost all organisms use the same basic building blocks to construct proteins. -often, the extent of two species' similarities can be predicted from their geographic closeness to each other. -a great deal of change has been observed among species that have experienced strong selective pressures through many generations. scientists have carefully considered and rigorously tested the observations listed above. when scientists offer a of these observations, they are making 1.) testable explanation, deductive explanation 2.) scientific interference, scientific law
