Answer :
Final answer:
Diseases like headlice, itch mites, ringworm, and nail fungus are caused by parasites and dermatophytes, which are types of fungi that break down keratin in human tissue.
Explanation:
Headlice, itch mites, ringworm, and nail fungus are all diseases caused by different types of parasites and fungi. Ringworm, athlete's foot, jock itch, and nail fungus, also known as onychomycosis, are common fungal infections. These conditions are caused by dermatophytes, a group of fungi that feed on keratin found in the skin, hair, and nails, but are not actually related to plants or worms despite the name. Conditions such as athlete's foot and jock itch are typically treated with over-the-counter topical creams and powders and are readily resolved, although sometimes more persistent infections may require prescription oral medications.
