<h3>Why is RNA the precursor to DNA?</h3>
The speculation that RNA preceded DNA and proteins in evolution. In the earliest cells, pre-RNA molecules could have had mixed genetic, structural, and catalytic features and those features could have progressively been changed with the aid of using RNA.
- The presence of the X form withinside the diffraction sample indicated to Franklin that DNA strands have been helical. Each sprint of the X form marks the repetition of atoms, or atomic repeats, in DNA
- Chargaff rule: The rule that during DNA there may be constantly equality in amount among the bases A and T and among the bases G and C. (A is adenine, T is thymine, G is guanine, and C is cytosine.) Named for the tremendous Austrian-American biochemist Erwin Chargaff (1905-2002) at Columbia University who found this rule.
- The crucial physiological roles performed with the aid of using the nucleic acid precursor rNTP and dNTP molecules in people has come to be obvious because the Nineteen Seventies with the aid of using the popularity of 28 exceptional inborn mistakes of purine and pyrimidine metabolism.

Answer:
The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.
Explanation:
The diagrammatic illustration in this question is showing a food web made up of a variety of species feeding on one another. As shown in the food web, sea otters are one of the top predators that can eat a wide variety of organisms.
Sea urchins feed directly on kelp, however, the population of sea urchins can be controlled by sea otters which feed on sea urchins. Hence, if population of sea otters declined, more sea urchins will be available to feed on the kelp population, hence, will DECREASE.
