Which of the following is an example of "unity in diversity"? the forelimbs of all mammals have the same basic structure, modified for different environments. the structure of dna is the same in all organisms. all organisms, including prokaryotes and eukaryotes, use essentially the same genetic code. all of the above are correct.

All of the above are correct.

Explanation:

When we think about organisms present in this world we wonder that how much diverse this world is from microscopic bacteria to huge trees. But even after this diversity the origin of every organism is same as all have evolved from single individual.

So every organism which looks different from each other have some similarities like they all have same DNA structure and use same genetic code for amino acids showing unity in diversity.

Same basic structures of forelimbs in mammals are modified for different environment which shows that they have common ancestor which is also an example of unity in diversity.

the aswer is letter c

the denominator has a very specific role.
