Question

Most of the life we see, including plants and animals are classified in the domain Eukaryota. Eukaryotic cells are more complex than prokaryotes, they contain organelles, and the DNA is linear and found within the nucleus. The complex eukaryotic cell enabled a whole new era of life on Earth, because these cells eventually evolved into multicellular organisms. But how did the eukaryotic cell itself evolve from a simple prokaryotic cell? Evidence supports the idea that eukaryotic cells are actually the descendants of separate prokaryotic cells that joined together in a symbiotic union - endosymbiosis.

What evidence supports the theory of endosymbiosis? More than one answer can apply.

A. Mitochondria and chloroplasts are similar to prokaryotes in that they do not have their own membranes.

B. Eukaryotic cells contain mitochondria and some contain chlorophyll. All contain ribosomes.

C. Mitochondrial DNA is most closely related to a parasitic bacteria called Rickettsia prowazekii, which causes epidemic typhus.

D. Both mitochondria and chloroplasts have a circular DNA genome, like a bacteria's genome, but much smaller. This DNA is passed from a mitochondrion to its offspring and is separate from the "host" cell's genome in the nucleus.

E. Both mitochondria and chloroplasts have their own ribosomes to produce proteins.

F. Eukaryotic cells were on earth before prokaryotic ones.

Answer 1

don't know bro It's hard

Answer 2

Answer:

1. Mitochondrial DNA is most closely related to a parasitic bacteria called Rickettsia prowazekii, which causes epidemic typhus.

2. Both mitochondria and chloroplasts have a circular DNA genome, like a bacteria's genome, but much smaller. This DNA is passed from a mitochondrion to its offspring and is separate from the "host" cell's genome in the nucleus.

3. Both mitochondria and chloroplasts have their own ribosomes to produce proteins.
