Question

what is an organism that carries and transmits pathogens to humans or other animals?

o protozoan
o vector
o fungal spore
o droplet

Explanation:

A vector is an organism that carries and transmits pathogens to humans or other animals. For example, mosquitoes can be vectors for diseases like malaria (transmitted by the Plasmodium protozoan carried by the mosquito). A droplet is just a small drop (e.g., of liquid like in respiratory droplets but not an organism). A fungal spore is a reproductive unit of a fungus. A protozoan is a single - celled organism (some can be pathogens but not the carrier/transmitter in the sense of a vector).

Answer:

Vector
