Lipids and proteins.
Lipids are macromolecules which provide insulation.
A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.
Proteins are biological macromolecule and mostly composed of enzymes.<span> Proteins play a role in the physical make-up of a cell or acts as a cytoskeleton –maintains cell shape and figure. These proteins plays different roles and works with nucleic acids and other macromolecules in the cells including cell cycle, cell adhesion, immune response and cell indicators. <span> </span></span>
Answer:
Decomposition dead organisms by fungi and bacteria remove sulfur groups from amino acids, producing hydrogen sulfide, returning inorganic sulfur to the environment.
Explanation:
Answer and explanation;
-Stem cells, Adult stem cells and skin cells , have a similarities and they may also differ in a number of ways.
-A stem cell has not gone through the process of differentiation, so they have the potential to become any type of cell.
-Adult skin cells have gone through differentiation and cannot become another type of cell. Same case applies to the skin cells, they have already undergone differentiation;
-Similarity; The cells that are taken from the same person would have the same DNA.
-Difference; The skin cells and the adult stem cells have already gone through differentiation, whereas embryonic stem cells have not. The different genes that the types of cells have are turned on and off causing the differences.
Well I guess that through all these 3 main elements we can identify the origins of someone and their identity
I mean I think that what is in common amongst these three is that they are identical to the person
