Answer:
b. such as RNA and DNA
Explanation:
DNA and RNA represent essential molecules present in all organisms. These nucleic acids (DNA and RNA) are composed of large chains of nucleotides that function to synthesize proteins required for cellular processes and to produce cell structures. Both RNA and DNA are highly stable biomolecules capable of storing and transmitting genetic information, which has been a requisite for the evolution of modern cells. Moreover, it is important to note that DNA is a double-stranded molecule and therefore it is more stable than single-stranded RNA.

The correct answer is D. Decrease in soil fertility.
<h3>Explanation:</h3>
A particular crop has a particular need for certain nutrients, and contributes a certain set of nutrients in return to the soil. When the same crop is planted over and over the years, the certain set of nutrients required to sustain are used up, and an accumulation of particular nutrients not essential for that particular plant's growth piles up. This leads to poor growth and development of the plant due to nutrient deficiency - and the quality of a soil to sustain growth and agriculture of a plant is known as fertility, which in this case decreases.
