Answer:
Stars form large groupings
Explanation:
A large group of stars that have a common origin and are gravitationally bound for some length of time is called star clusters. Star clusters provide a way to study the ages of stars and stellar evolution. There are two categories of star clusters i.e. galactic clusters, and globular clusters.
Out of the given options, we can say that the correct option is (b) "Stars form large groupings".

There are two main reasons. First, there are introns and exons existed in eukaryotes. Introns do not contain the genetic information but are in large amount in chromosome. So, if the mutation occurs in the introns, it will be recessive. Second, one amino acid will corresponding to several base sequences. For example, UUU and UUC all represent Phe. This is called degeneracy. So if the mutation did not change the amino acid, it is also recessive.
        
             
        
        
        
Yes! This is because of the law of thermodynamics which suggests that as energy is transferred or relayed into other forms of energy, entropy increases. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
