Even though sound waves in water and sound waves in air are basically similar, the way that sound levels in water and sound levels in air are reported is very different, and comparing sound levels in water and air must be done carefully.
Melanocytes are found in the stratum basale layer. About 1 in every 5 to 10 cells in this layer is a melanocyte. Melanocyte number is the same in all races. In different races, the number of melanocytes is THE SAME. In light skinned people, the melanin is concentrated deep in the epidermis, particularly in the stratum basale layer. Differences in skin colour depend on how much melanin is produced, the size of the melanosomes, and the degree to which they agregate.
Merkel cell. Merkel cells are found in the skin and some parts of the mucosa of all vertebrates. In mammalian skin, they are clear cells found in the stratum basale (at the bottom of sweat duct ridges) of the epidermis approximately 10 Âµm in diameter.They also occur in epidermal invaginations of the plantar foot surface called rete ridges.n mammalian skin, they are clear cells found in the stratum basale (at the bottom of sweat duct ridges) of the epidermis approximately 10 Âµm in diameter.
