The mosaic nature is due to the numerous proteins that
are entrenched in the phospholipids bilayer, fluctuate in shape, size and
patterns in the same way as the stones or tiles of a mosaic.
the flexibility is due to individual phospholipids molecules which can move virtual
to one another and gives the membrane a flexible structure that is constantly
changing shape

DNA replication is the process by which a double stranded DNA molecule is copied to produce an identical DNA molecule. The process takes place in the nucleus of a cell and is undertaken by enzyme DNA polymerase. It is the first stage of the central dogma of life then followed by transcription process and the translation. Translation is the process that occurs after DNA replication where the DNA molecule formed from replication is used as a primer for the formation of a messenger RNA.
Acidity in human sweat is an example of<u> </u><u>innate immunity</u>
Explanation:
Sweat arising from human skin is acidic in nature with a pH ranging between 4.5 to 7.
As part of innate immunity, the skin acts both as a physical barrier and chemical shield.
As part of chemical shield, the skin’s sebaceous glands present on the skin produces an oily substance called sebum which contains free fatty acids. Further, hair follicles on skin releases lactic acid which bind with the amino acids of the proteins present on the keratinized layers of skin. The acidity of the sweat is due to the combined action of free fatty acids, lactic acid and the amino acids present on the skin.
This natural acidic nature of skin creates a hostile acidic environment to pathogens which prevents their entry into the body.
