One piece of evidence for the endosymbiotic theory is that the mitochondria and chloroplasts of eukaryotes _____.. . A.self-repl
icate by binary fission, which is the way prokaryotes divide. B.have DNA similar to prokaryotes. C. synthesize proteins like prokaryotes. D.all of the above
Mitochondria and chloroplasts have striking similarities to bacteria cells. They have their own DNA, which is separate from the DNA found in the nucleus of the cell. And both organelles use their DNA to produce many proteins and enzymes required for their function. A double membrane surrounds both mitochondria and chloroplasts, further evidence that each was ingested by a primitive host. The two organelles also reproduce like bacteria, replicating their own DNA and directing their own division.
A photon of light takes only eight minutes to get to the Earth from the surface of the Sun. But it can take 100,000 years from the core of the Sun to get to the surface. Where it bursts out and flies at the speed of light.
