Caused by Dirofilara immitis, heartworms are a potentially fatal parasitic worm living in the pulmonary arteries, lungs & hearts of cats. Heartworms are nematodes, a type of roundworm, they are several inches long, thin & white. Heartworms are a common parasite in dogs, although cats do become infected & may develop disease. While cats are more resistant to heartworm infestations than dogs, cats in particular are extremely vulnerable to heartworm & even a small number can lead to death. The disease is spread from mosquito to animals when the mosquito feeds from it's host. This is known as vector borne.
A unit vector is a vector whose magnitude is one. Vectors can have magnitudes that are bigger or smaller than one so they would not be unit vectors.
Viruses are generally used as that type of vector here.

Sound waves are transmitted in this manner.
Because it's a type of velocity and velocity is vector quantity
The measurement of 30 minutes is a measurement of time.
Vector
A vector has magnitude and direction, so since it is up it is vector.
Puc18, i believe, is both. It is a plasmid vector. Plasmid is a more descriptive as it is a type of vector. Similarly to how a cheetah is both a mammal and an animal.
