Another version of the maze, which was used by scientists, is a comb of 15 end points. The further the bait is from the entrance, the more time the scout needs to describe the path to the foragers. But if you place a bait on any branch more often, then the ants begin to use this branch as a new point of reference. If branch number 10 is often used, then a little more than 10 times are spent to describe the path to 11 branches — that is, ants describe the path as “10 + 1”. And exactly the same result in time shows a twig 9 - that is, "10-1". This is reminiscent of the Roman system of calculus - X, XI, IX. So scientists have proven that ants are able to add and subtract.

Nucleic acids are macromolecules made up of smaller molecules called nucleotides. There are two types of nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleotides are linked together by means of links forming a chain. The nucleotides of DNA are called thymine (T), adenine (A), cytosine (C), and guanine (G). DNA differs from RNA in that it contains a T, while RNA includes a uracil (U) in its place. Although each organism’s DNA is unique, all DNA is composed of the same nitrogen-based molecules. But then, how does DNA differ from one organism to another? it depends on how these molecules are arranged and this differs among individuals. https://www.nature.com/scitable/topicpage/dna-is-a-structure-that-encodes-biological-6493050/ Clark, David P.
