The symbiotic relationship between moss and a tree is commensalism
The most probable and most likely answer to this problem would be genetic engineering.
Since this talks about scientists having recently modified the bacteria that cause tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid, it has now altered the genetic composition of the bacteria. Genetically engineering bacteria and viruses have their advantages and, of course, disadvantages, either direct ones or long term ones. Genetic engineering would prove that it would be one of the many weapons that we could use to counter problems in the coming future.
Answer:
Nitrogen in the reduced form is the major component of the three most important biological macromolecular structures: (i) proteins/polypeptides, (ii) DNA and RNA, and (iii) polymers of amino sugars.
There are four major classes of biological macromolecules - carbohydrates, lipids, proteins, and nucleic acids. Each are made up of different elements. Nitrogen is found in two of these macromolecules - proteins and nucleic acids.
Nitrogen is a naturally occurring element that is essential for growth and reproduction in both plants and animals. It is found in amino acids that make up proteins, in nucleic acids, that comprise the hereditary material and life's blueprint for all cells, and in many other organic and inorganic compounds.
