Rank the test tubes in order of greatest amount of digestion to least amount of digestion. For each tube, explain why it would have exhibited that level of digestion.

How could the experiment be modified to further test human digestion actions? What variables would you change? What would you keep the same?

In which test tube was the activity most like that of a real human stomach? Explain.

this online thing is really killing me so please help

(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
