Interfaces in Object Oriented Programming Languages. An interface is a programming structure/syntax that allows the computer to enforce certain properties on an object (class). For example, say we have a car class and a scooter class and a truck class. Each of these three classes should have a start_engine() action.
The epidermis is the very outer layer of the skin that provides protection from bacteria (thanks to it's pH level), becoming overloaded with water (it's waterproof) and from heat loss. It has four of five distinct layers to achieve this.
The epidermis is made up of two main layers. The upper layer is called the stratum corneum and is comprised of dead epithelial (skin) cells. This layer provides protection to â¦ the body and makes the skin water-resistant.The lower layer is called stratum germinativum.Stratum germinativum is where new epithelial (skin) cells are made.he upper layer is called the stratum corneum and is comprised of dead epithelial (skin) cells.
