What is the pressure at the bottom of the water layer?
The pressure at the bottom of a water layer increases with depth due to the weight of the water column above. This pressure is calculated using the formula P = ρgh, where P is pressure, ρ is the density of water, g is the acceleration due to gravity, and h is the depth of the water layer.
What are the different layers and structures visible in a skin cross-section?
In a skin cross-section, the different layers and structures visible include the epidermis (outermost layer), dermis (middle layer), and subcutaneous tissue (innermost layer). The epidermis contains layers of cells, including the outermost layer of dead skin cells. The dermis contains blood vessels, nerves, hair follicles, and sweat glands. The subcutaneous tissue is made up of fat cells and connective tissue.
What is they layer of tissue underneath epidermis and hypodermis?
The skin layers from top to bottom are the epidermis (top layer), dermis (middle layer), and hypodermis (bottom layer).
What is another name for a protective underlying layer?

Which layer of skin is the primary site of mitosis?
The stratum basale, also known as the basal layer or germinative layer, is the primary site of mitosis in the skin. This layer is located at the bottom of the epidermis and is responsible for producing new skin cells through cell division.
What is the bottom layer of skin?
The bottom layer of the skin is called the subcutis or hypodermis. It is composed mainly of fat and connective tissue, serving as a cushion and providing insulation for the body. The subcutis also contains major blood vessels and nerves that supply the skin and underlying structures.
