What else can I help you with?
Hair and nails are the modification of what?
The epidermis.
What modification does the hair and nails have?
epidermis
What layer of the epidermal region has scalelike cells full of keratin that constantly flake off?
The outer layer of the epidermis is full of scale like that frequently flake off. These cells are pushed to the surface as they begin to die.
Gaseous exchange occurs in plants through these strutures in the epidermis?
The structure in the epidermis that gaseous exchange occurs in plants is through the stomata. A stomata is a tiny opening or pore in the epidermis.
What structure is responsible for the strength of attachment between the epidermis and dermis?
epidermal ridge
What system has dermis and epidermis?
The skin system has both dermis and epidermis layers. The epidermis is the outermost layer of skin and provides protection, while the dermis is underneath and contains blood vessels, nerves, and structures such as hair follicles and sweat glands.
What are similarities in the structures found in the epidermis with the structures found in the dermis?
There is no structural similarity between the epidermis and the dermis. They are both a part of the integumentary system but are vastly different in structure and makeup.
How does the epidermis of the root differ from the epidermis of the stem in structure and function?
"As you recall, epidermis (1) is the outermost cell layer of leaves, roots and stems. Unlike the root epidermis, stem and leaf epidermis contain stomata (more on stomata when we discuss photosynthesis). In many plants, leaf and stem epidermis is covered by a wax-like layer of cutin, which protects the plants from excessive water loss, and from pathogen attack."
Why removing the lower epidermis layer of the leaf and not the upper epidermis?
Removing the lower epidermis layer allows for easier observation of stomata and overall leaf structure. Stomata are mostly located on the lower epidermis, which regulates gas exchange for photosynthesis. Additionally, removing the upper epidermis may damage the leaf's cuticle, which can affect its ability to retain water.
What are Food that are chemical change?
Any modification in the chemical structure of foods is a chemical change.
Scalelike cells full of keratin that constantly flake off?
stratum corneum
What is the scalelike part in the medial wall of orbit?
lacrimal bone
