The epidermis will not be connected to the dermis.

Answer 1

The correct answer is: E. The epidermis will not be connected to the dermis.

Step-by-step explanation:

The basal lamina is part of the epithelium and is also secreted by its cells to act as a point of attachment for cells. It has two layers, a lucid one that contains laminin (a glycoprotein) and a dense one that is composed of type IV collagen. If the basal lamina is not in the skin to affix the dermis and the epidemis, these will not be connected with each other.
