<span>It is believed that in the evolutionary history of life on Earth, there was the RNA world before DNA and proteins.</span> <span>RNA is a self-replicating molecule that can store and replicate genetic information and catalyze (ribozymes-RNA enzymes) reactions that are important for life. Because of these characteristics, it is possible that RNA world really existed. Because of the better stability and durability than RNA DNA later it became the predominant storage molecule.</span>

Marketing is one of the most important factors in determining the success of any fruit and vegetable farming enterprise. Marketing includes all the operations and decisions made by producers. These decisions range from deter-mining the most marketable crops for production to deciding how to best deliver quality produce to the consumers at a profit.

However, as more organic producers enter the industry and it becomes more and more competitive, existing producers are forced to become better growers and more effective marketers.
There were several characteristics that the scientists kept in mind while classifying, these are mobility, cell structure, cell type, body type, etc.
<h3>What is classification?</h3>
Classification is the grouping of organisms based on similar characteristics which makes them different from other groups.
There are the following characteristics to classify them:
- Mobility: it includes whether the organism is moving or sessile.
- Cell type: it includes eukaryotic or prokaryotic cells.
- Cell structure: it includes whether the cells have a cell wall or not.
- Body type: it includes whether the organism is unicellular or multicellular.
- Mode of nutrition: It includes whether the organism is parasitic, autotrophic, symbiotic, consumer, etc.
Thus, these are the characteristics that the scientists kept in mind before drawing classification.

Answer:
Density is a physical property of matter, as each element and compound has a unique density associated with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume.
