Answer 1

Eschar defines the dead tissue that rests on top of third-degree burns, appearing as dark sloughed off skin and results from significant tissue damage.

Step-by-step explanation:

The term eschar refers to B. The dead tissue lying on top of third-degree burns. Eschar is a slough or piece of dead tissue that is cast off from the surface of the skin, particularly after a burn injury. This dead tissue is typically black or brown and is a result of the skin cells being deprived of blood flow and dying, which occurs in severe third-degree burns. These types of burns extend through the entire epidermis and dermis, destroying the tissue and the nerve endings, which may require medical intervention such as excision or skin grafting.
