Question

1. the layer of the skin that is constructed of nonliving keratinized cells is termed the:

basement membrane
dermis
epidermis
subcutaneous layer

Explanation:

The epidermis is the outermost layer of the skin. It is composed of multiple layers of epithelial cells. The cells in the outermost part of the epidermis, specifically in the stratum corneum, are non - living and keratinized. Keratin is a tough, fibrous protein that provides protection.
The basement membrane is a thin layer that separates the epidermis from the dermis. It is not composed of keratinized cells.
The dermis is the layer beneath the epidermis. It contains connective tissue, blood vessels, nerves, hair follicles, and sweat glands. It is not made up of non - living keratinized cells.
The subcutaneous layer (hypodermis) is mainly composed of adipose tissue and connective tissue. It is not the layer with non - living keratinized cells.

C. Epidermis
