Respuesta :

5. b. eukaryotic cells.
7. 
c. Mitochondria have their own set of DNA molecules.

Answer:

Q 5. b. eukaryotic cells.

Q 7. c.  Mitochondria have their own set of DNA molecules.

Explanation:

Eukaryotic cells are assumed to be originated from the prokaryotic cell. It was assumed that a bigger prokaryotic cell engulfed a smaller prokaryotic cell but it was not digested. Both lived in symbiotic associations with each other and evolved to form eukaryotic cells.

The best example is seen in mitochondria and chloroplast in eukaryotic cells. Both are assumed to be of prokaryotic origin because both shows the similarity to prokaryotic cell such as having their own DNA, 70s ribosome and double membranous structure.

Therefore the correct answer for question 5 is b.  eukaryotic cell and for question 7 is c.  Mitochondria have their own set of DNA molecules.
