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 the outer layer of skin, which is composed of several layers of cells. It provides a barrier of protection from foreign substances. The epidermis is thickest in large animals like horses.It includes multiple types of cells, including keratinocytes, melanocytes, Langerhans cells, and Merkel cells.Each of these cells has special functions. Keratinocytes provide a protective layer that is constantly being renewed in a process called keratinization.In this process, new skin cells are created near the base of the epidermis and migrate upwards.ach of these cells has special functions.
