The term mosaic is used in arts for an art piece that is composed of many small pieces of materials like stones or glasses. However, in biology it is used for a structure that is made up of different types of cells.
Now if we have to describe a biological mosaic structure , then there is no perfect option than the structure of a cell membrane of animals' cells. Cell membrane is not made up of two types of cell at all but it is a structure that is composed of a lipid bilayer in which proteins are floating as you can see in picture.
The structure was explained as mosaic by fluid mosaic model. If we take a deep look, the double layer of lipids are made up of phospho lipids, which contain two fatty acid tails and a lipid head. The heads are hydrophilic and are outside while tails are hydrophobic and they are inside. This structure has alot of importance as per the function of cell membrane because it maintains the cell's internal environment and separates it from outer environment. This is because
As cell is surrounded by an environment which contain water in excessive amount, therefore nature has made cell membrane in a way that hydrophobic tails do not face water and stay inside the double membrance while hydrophillic heads face the water region outside the cell as well as inside the cell (cytoplasm that contains alot of water content too).
Hope it helps!
Answer:
The correct answer is a. Human papillomavirus
Explanation:
Human papillomavirus is the most common STI according to the center for disease control and prevention. It can pass from one people to another people from skin contact. They are responsible for causing condylomata( genital warts) in the patients.
The genital HPV infection is mostly caused by direct sexual contact with the infected person. HPV infection later can cause cancers like cervical cancer, genital cancer, throat cancer, etc if not treated properly.
Therefore students demonstrate an understanding of the material when they identify human papillomavirus as a cause of condylomata.
