Answer:
Some organisms have a tremendous amount of noncoding DNA, like repetitive sequences.
Explanation:
DNA is the genetic material in almost all the living organisms but except in case of viruses that has RNA as their genetic material. DNA consists of the four nitrogenous bases, pentose sugar and phosphate group.
Prokaryotes have simple body organization and structure because of the sall amount of DNA. Eukaryotes have complex body organization because they have large amount of the transposons, repetitive sequences and non repetitive DNA sequences.
Thus, the correct answer is option (b).

<span>Ecologists study populations by studying changes in growth rates, distributions and genetic compositions. I think through population studies, ecologists can get an idea about the conditions that are influencing the populations being studied. They can also discover how these changes would impact other interacting populations.</span>
