Which evidence supports the endosymbiotic theory? Select all that apply. Mitochondria and chloroplasts have a separate, simpler DNA from the nucleus DNA of a eukaryotic cell. These organelles' DNA resembles the DNA of prokaryotic cells. Observations of prokaryotic cells engulfing other prokaryotic cells and the engulfed cells becoming the organelles have been recorded. Mitochondria and chloroplasts self-replicate by a cell division process similar to binary fission, which is the way prokaryotes divide. The way mitochondria and chloroplasts synthesize proteins within the eukaryote cell is more similar to prokaryotes than to eukaryotes. There are living examples of prokaryotes, like cyanobacteria, that share similar features with both mitochondria and chloroplasts of eukaryotic cells.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
