In terms of Epidemiology a vector is an organism which transmits diseases to healthy organisms.
A biological vector develops an infected organism in its body and passes it along to its host. e.g mosquito while a mechanical vector carry an infected organism to its host through its legs and other body parts. e.g flies.
Two mechanical vectors carry foreign DNA into the nucleus of a cell.
there are two types of vectors cloning vector and expression vectors.
Vectors play very important role in spread of many diseases. The microorganism spends dominant or recessive stage of it's life cycle. Without the vector the disease can not spread in most of the cases. Malaria and plague are two important vector born diseases.

biotic barriers to dispersal/establishment (ex. competition, pollination vectors)
Biological vectors include viruses as well as plasmids.
Micro-pipettes can be mechanical vectors for disease. Since they do not carry the disease like a living organism, they cannot be considered to be a biological vector. If the pipette is not sterilized properly, the result can be a mechanical vector for a disease.
What are difference between scalars and vectors
Without the difference between scalars and vectors the Universe doesn't work !
Examples of Biological Vectors: Tick - Lyme Disease Mosquitoes - Malaria Sand fly - Leishmania Mechanical Vectors Housefly picking up salmonella with its feet and depositing it on human food
Coplanar :The vectors are in the same plane.Non coplanar :The vectors are not in the same plane.
Vectors have a direction associated with them, scalars do not.
Coplanar :The vectors are in the same plane.Non coplanar :The vectors are not in the same plane.
Coplanar :The vectors are in the same plane.Non coplanar :The vectors are not in the same plane.
All vectors that are perpendicular (their dot product is zero) are orthogonal vectors.Orthonormal vectors are orthogonal unit vectors. Vectors are only orthonormal if they are both perpendicular have have a length of 1.
180 degrees. Then the sum of the two vectors has a magnitude equal to the difference of their individual magnitudes.
Vectors are thread safe but array lists are not. Hence array lists are faster than Vectors.
