Explanation: There is only a certain of DNA that is unique in the organism. Rest of the DNA is same in all the organism.
Suppose at any crime place where there is some evidence having the DNA , this DNA sequence is matched with the DNA sequence of the criminal. This of the DNA is used in the DNA fingerprints to detect the person having the same DNA sequence. The matched sequence of DNA will be of criminal.
So, this is how the DNA fingerprints can be used in many cases as it is unique in the organisms.
It makes sense that cell membranes are made of phospholipids because water cant mix in with lipids, so the phospholipids will be able to effectively block out any unwanted water or chemicals suspended in water outside of the cell.
