The answer is B because <span>completely burning anything usually results in carbon being produced there for any gases such as oxygen which make up the molecule would be destroyed or recombined...since I know nothing about the environment in which it is burning such as open or closed vessel this suffices the question in assuming some mass would be lost as gases and/or not be part of the new molecule.</span>
Direct Observation. Hope this helps!
The skeletal structures of both the bats and the humans developed from the same embryonic tissue for the main reason that both of these skeletal contains the humerus, radius, ulna, and the five digit bones. In addition, the main difference that these structures have is that the bat's wing is longer compared to the human arm.
