The level of organization that reflects the interactions between organ systems is the organism.
<h3>What is Organism ?</h3>
In biology, an organism is any organic, living system that functions as an individual entity. All organisms are composed of cells. Organisms are classified by taxonomy into groups such as multicellular animals, plants, and fungi; or unicellular microorganisms such as protists, bacteria, and archaea.
Producers, consumers, herbivores, carnivores, omnivores, scavengers, parasites, predators, and decomposers are only a few of the various sorts of creatures or organisms.
There are many different kinds of organisms on Earth, some of which are complex, such as plants and animals, and which are multicellular because they include a lot of cells.
- But not every organism is the same. Some, like bacteria or algae, are distinguished by having just one cell.
- However, not every organism has the same kind of cell. Prokaryotic cells, or cells without a clearly defined nucleus, are present in some.
- However, not every organism has the same kind of cell. Prokaryotic cells, or cells without a clearly defined nucleus, are present in some. An creature having prokaryotic cells includes things like: Bacteria, Eukaryotes, which are cells that do have a distinct nucleus, can be found in humans, plants, and animals.
So lastly we can say that, the organism is the level of organization that depicts the interconnections between organ systems.

Answer:
Collagen is an extracellular matrix protein and one of the most abundant protein in the body. Its triple-helical structure is a result of the 3 coiled chains. Each chain mainly comprises of Glycine, Proline and Hydroxyproline. The Glycine hydrogen bonds with residues of the adjacent chain while the proline and hydroxyproline C-N bonds provide stability in the structure.
Explanation:
The structure of the plasma membrane;
The plasma membrane is composed of a bilayer of phospholipids. A molecule of phospholipid consists of two fatty acids and a phosphate group attached to a glycerol component. The fatty acid tails represent a hydrophobic region of the molecule, while the glycerol-phosphate head is hydrophilic. The phospholipids are arranged into a bilayer formation with the hydrophilic heads pointing to the outside and the hydrophobic tails pointing toward the inside. The plasma membrane is a barrier to most molecules. In plants, fungi, and bacteria, the membrane deposits cellulose or other polysaccharides on the outside of the membrane to create a cell wall, which it provides support to the cell.
Embedded in the phospholipid bilayer are various proteins and, in animals cells, cholesterol molecules. This mixture of molecules accounts for the fluid mosaic model of the plasma membrane, that is, a highly flexible lipid boundary impregnated with various other molecules.
The interactions of plasma membrane with the outside environment;
The plasma membrane is a selectively permeable membrane. Small molecules, like O2 and CO2, readily diffuse through the membrane. The movement of larger molecules is regulated by proteins in the plasma membrane. There are several kinds of these proteins. Channel proteins provide passage for certain dissolved substances. Transport proteins actively transport substances against a concentration gradient. The glycocalyx, consisting of the oligosaccharides from glycolipids, recognition proteins, and other glycoproteins, provides adhesion or
participates in cell-to-cell interactions. Receptor proteins recognize hormones and transmit their signals to the interior of the cell.
Various substances can be exported into the external environment by exocytosis. In exocytosis, substances are packaged in vesicles that merge with the plasma membrane. Once they merge with the membrane, their contents are released to the outside. In an opposite kind of procedure, food and other substances can be imported by
endocytosis. In endocytosis, the plasma membrane encircles the substance and encloses it in a vesicle.
Both the nitrogenous base and phosphate group are attached to the deoxyribose sugar in DNA.
