E)epidermis.

Answer 1

The epidermis is the layer of the skin that provides a barrier against bacteria, chemicals, and mechanical injuries. It acts as a protective barrier by preventing water loss, invasion by pathogens, and abrasion. The most superficial layer of the epidermis, known as the stratum corneum, plays a crucial role in preventing the penetration of microbes and dehydration of underlying tissues.

Step-by-step explanation:

The layer of the skin that provides a barrier against bacteria as well as chemical and mechanical injuries is the epidermis. The epidermis is the outermost layer of the skin and acts as a protective barrier against water loss, invasion by pathogens, and abrasive activity. It consists of several layers, with the stratum corneum being the most superficial layer that helps prevent the penetration of microbes and dehydration of underlying tissues.
