Answer 1

(6): Seroprevelence refers to the level of pathogens in blood serum. Therefore, detection with antibody is a sign of active infection. TRUE

(7): Herpesvirus has 8 species are known that effect human. Option (1).

(8): Zootonic deseases are deseases that are spread between human and animals. Around 60 % human pathogens are zootonic. Option (d).

(9): OPtion (a). Manatee cannot hear boat.

(10): Audiogram is a graphical represntation of a person's hearing levels. A dip shows noise induced hearing loss. Option (c) Range of loudest sounds.
