Hi!
14. Star clusters are held together by gravity. It really depends how old a star in the cluster is - it could be just born, or could have been born hundreds of billions of years ago. Astronomers categorize them by different colors, temperatures, sizes, brightness, etc.
15. Open clusters eventually disperse to form field stars.
16. Our sun is not part of a cluster (although it used to be).
17. Globular clusters<span> </span>are<span> found in the ring of a galaxy and usually contain more stars and </span>are<span> much older than the </span>open clusters.
18. Omega Centuari and M13.
Hope this helps!

Let's make a Punnett square for this:
Let F - Freckles
f - no freckles
Father: Ff
Mother: ff (She has no freckles, meaning she does not have the dominant allele)
F f
f Ff ff
f Ff ff
The count would then be 2/4 with freckles and 2/4 without freckles. So the percentage of would be 50% with freckles and 50% without freckles.
