I think Option (3)
The arms mostly contains old blue and blue-white stars
Explanation:
Spiral arms are the regions in stars extending from the middle of spiral galaxies and the barred spiral. Those long, thin areas look like a spiral and therefore give their name to spiral galaxies.
Spiral arms, though, include many young, blue stars, that render their arms so bright (due to the high mass density and the fast stellar forming rates).

Chloroplasts and mitochondria are both involved in energy conversion in cells. Select the other similarity they share. Question
Afina-wow [57]

Chloroplasts and mitochondria are similar in the sense that they both contain DNA.

MITOCHONDRIA AND CHLOROPLAST:

  • Mitochondria is a membrane bound organelle found in eukaryotic cells. Mitochondria is the energy production site of cells because it is where cellular respiration takes place.

  • Chloroplast is another membrane-bound organelle in eukaryotic cells. They are the site of photosynthesis in plants.

  • Mitochondria and chloroplast are both involved in energy conversion in cells because electron transport chain occurs in both organelles.

  • However, another similarity between these two organelles is that they contain extra-chromosomal DNA.
