One piece of evidence for the endosymbiotic theory is that the mitochondria and chloroplasts of eukaryotes . a. self-replicate 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.

the correct answer is 2 and 4

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
