cell membrane
No, the basement membrane is not a living layer. It is a thin layer of extracellular matrix that separates and anchors epithelial and endothelial cells to the underlying connective tissue.

The outer non-living layer of plant cells is called the cell wall. It provides structural support and protection to the cell, as well as helps regulate the movement of substances in and out of the cell.
No, they cannot be blocked. The Ozone layer can only block the UV rays of the sun.
The cells that make up the epidermis are both living and dead. The top layer of the epidermis, known as the stratum corneum, is made up of dead cells called corneocytes. However, the lower layers of the epidermis contain living cells that are actively dividing and producing new skin cells.

Stratum basale is the layer of skin that has living and dividing cells.
The dermis is the layer of skin that contains only living cells. The epidermis contains both living and dead cells.
stratum granulosum, stratum spinosum, and stratum basale.
The outer layer of the skin, called the epidermis, is mostly made up of dead skin cells called keratinocytes. However, the deepest layer of the epidermis contains living cells that are responsible for producing new skin cells.

yes the cell membrane is the protective layer around cells that's underneath the cell wall.
The outer non-living layer of plant cells is called the cell wall. It provides structural support and protection to the cell, as well as helps regulate the movement of substances in and out of the cell.
Skin is primarily composed of living cells, but the outermost layer, known as the stratum corneum, consists of dead skin cells. These dead cells are essential for protective functions, forming a barrier against environmental damage and pathogens. Underneath this layer, living cells continuously regenerate, pushing older cells up to the surface where they eventually die and are shed. Thus, while the outermost layer is made of dead cells, the skin as a whole contains both living and dead cells.
