Mitochondria provide evidence that eukaryotic cells evolved through endosymbiosis. What features of mitochondria support this theory? A. Mitochondria have been found throughout the fossil record.
B. Mitochondria contain their own DNA and are similar in size to bacteria.
C. Cells that contain mitochondria also contain chloroplasts, and chloroplast membranes are similar to bacterial membranes.
D. Mitochondria can be produced when sparks of electricity are passed through an environment of gases similar to the conditions of early Earth.

(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
