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.
The enveloped virus make the cell think that they just found a jackpot of protein, only to find a virus inside to take over the system, like the trojan horse.
Answer:
The correct answer is - Chondroblasts; Fibroblasts
Explanation:
Mesenchymal progenitor cells will form chondrocytes combinedly called Chondroblasts that is responsible for the secretion of the rubbery matrix of cartilage.
Fibroblast on other hand produces fibers and ground substance. These ground substances and fibers make the matrix of the fibrous connective tissue.
