In the scenario give above, the disease reservoir is the PARROT and the possible transmission method is INDIRECT CONTACT THROUGH AIR.
Disease reservoir refers to a source of a particular pathogen in an environment. A disease reservoir can be a person, an animal or an inanimate object like soil. In the case given above, the parrot is the disease reservoir and it passes the disease pathogen to the student. Pathogens are transmitted through four distinct ways, these are: direct contact, indirectly through the air, indirectly through contaminated object and through vectors. The disease pathogen was possibly passed to the student when the parrot was talking via tiny mucus droplets that escape from the bird's mouth.

The type of food to avoid after any type of surgery are any fast food or foods high in fat and grease and microwave food (frozen items). Frozen items should be avoided and fresh items should be gotten.

Butterflies are among the most vibrant insects, with colorations sometimes designed to deflect predators. New research shows some of these defenses may be driven by enemies one-tenth their size.
3.) the circulatory system
I don't know much about the cell cycle and cell division, maybe this will help!
