1) A quantity, such as the velocity of an object or the force acting on an object.

2) An organism, such as a mosquito or tick, that spreads pathogens from one host to another

3) A bacteriophage, plasmid, or other agent that transfers genetic material from one cell to another

- carriers of pathogens
What must happen for a pathogen to be transmitted by a mosquito vector:

- The pathogen must migrate to the mosquito salivary gland and replicate there.

- Only the Anopheles species of mosquito can transmit malaria

- The female bites
How do lice remain attached to their host:

- Legs, claws, and teeth that are adapted to grasp
Name a disease transmitted by flea vectors:
- - plague
- - typhus
Name a disease transmitted by Tick vectors:
- - lyme
- - Rocky Mountain spotted fever
Name a disease transmitted by Mosquito vectors:

- Malaria
Name a disease transmitted by lice vectors:

- Trench fever

- Typhus

- Relapsing fever
Name a disease transmitted by mite vectors:

- Allergic reactin (rash/itch)
How do mites directly cause disease:

- Burrow into the skin and induce an intense allergic response.
Name 2 organisms, their diseases, and the tick vectors that spread them:

1) Dermacentor andersoni; transmitts Rickettsia rickettsit (Rocky Mountain spotted fever)

2) Ixodes scapularis; transmitt Borreliaburgdorferi (Lyme Disease)
