Answer

8. Keratin. Explanation: Keratin is a fibrous structural protein that makes up the outer layer of human skin (the epidermis), as well as hair and nails, providing a waterproof and protective barrier. 9. Connective tissue. Explanation: Most connective tissues, such as loose connective tissue and dermis, are highly vascular, meaning they have a rich blood supply (with the exception of cartilage). 10. Matrix (or Ground Substance). Explanation: The intercellular substance in connective tissue consists of a ground substance and fibers, which together are called the extracellular matrix. 11. Neuron. Explanation: The neuron is the primary functional cell of the nervous system, responsible for transmitting electrical signals throughout the body. 12. Muscle tissue. Explanation: Muscle tissue is specialized for contraction, which produces movement of body parts or substances through the body.
