Explanation:

Question 73

The nail plate is the visible part of the nail and is made up of about 100 layers of flattened, dead nail cells. Nail folds are the skin folds around the nail, lunula is the white crescent - shaped area, and nail bed is the tissue under the nail plate. So the correct option is the one related to the structure made of about 100 layers of nail cells.

The stratum corneum is the outermost layer of the epidermis, which is the layer of skin visible and treated by cosmetologists. Stratum spinosum is a deeper layer of the epidermis, melanin is a pigment, and keratin is a protein. So the correct option is the one that is the visible outer layer of the skin.

Inflammation is a response to injury or infection and is characterized by symptoms like redness, heat, pain, and swelling. Decreased blood flow, chilling of tissue, and numbness are not typical characteristics of inflammation. So the correct option is the one that is a classic sign of inflammation.
