The layer of bedrock is called LITHOSPHERE.
Lithosphere is the rigid outer part of the earth which is made up of crust and upper mantles.The geologic processes that usually occur on the earth surface such as earthquakes are originated from the lithosphere. The lithosphere is bounded by the atmosphere above and the asthenosphere below.
Your answer should be tissues.
Answer: Epithelium tissue refers to the sheets of cells that cover exterior surfaces of the body, lines internal cavities and passageways, and forms certain glands. Connective tissue binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body. Muscle tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart. Nervous tissue is also excitable, allowing the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body
