The epidermis

A) is thicker than the dermis.
B) contains no blood vessels.
C) is composed of loose connective tissue.
D) is made up mostly of melanocytes.
E) is composed of the reticular and papillary layers.

The epidermis contains no blood vessels, distinguishing it from the dermis, which is vascularized. The epidermis is primarily made up of keratinocytes, not melanocytes, although melanocytes are present. It is thinner than the dermis, not composed of loose connective tissue (that describes some of the dermis), and does not include the reticular and papillary layers, which are parts of the dermis.
