lupus
eczema
filariasis
impetigo

worm
mosquito
tick
bird

question 15
___ is a condition of dry, fish - like skin.
papillomatosis
cicatrix
xeroderma
ichthyosis

Explanation:

• Question 13: Impetigo is a common bacterial skin infection. It often presents with vesicles (small fluid - filled blisters) or sacs that rupture and form a golden - yellow crust. Lupus is an autoimmune disease, eczema is a non - bacterial skin inflammation (atopic or contact - related), and filariasis is a parasitic disease (caused by worms).
• Question 14: Rocky Mountain Spotted Fever is caused by Rickettsia rickettsii, which is transmitted by ticks. Mosquitoes transmit diseases like malaria (Plasmodium) or Zika (virus), worms are not the vectors for this rickettsial disease, and birds are not the vectors for Rocky Mountain Spotted Fever.
• Question 15: Ichthyosis is a condition characterized by dry, fish - like skin. Papillomatosis is related to the growth of papillomas (benign tumors), a cicatrix is a scar, and xeroderma (like xeroderma pigmentosum) is more related to DNA repair defects and photosensitivity rather than the fish - like skin texture of ichthyosis.

Answer:

• Question 13: Impetigo
• Question 14: tick
• Question 15: Ichthyosis
