Answer:
Explanation:
The impairment of ciliated cells due to smoking causes an adverse effect on the respiratory track. This action reduces the efficiency and performance of the said track,thereby exposing it to infections and diseases. Little infection which the respiratory track would have been able to resist will become chronic due to the weakening of the ciliate cell.
Same applies to the digestive system the intake of painkillers do impair peristalsis.While peristalsis is the contraction and relacation of the stomach muscles during digestion .

A family of objects that all understand and respond * to the same methods is defined by a:class.
A method in object-oriented programming (OOP) could be a procedure related to a message and an object. An object consists of state data and behavior; these compose an interface, which specifies how the item could also be utilized by any of its various consumers.
A technique may be a behavior of an object parametrized by a consumer. The object is the actual component of programs, while the category specifies how instances are created and the way they behave. method: a technique is an action which an object is ready to perform. sending a message.
Sending a message to an object means asking the thing to execute or invoke one in all its methods. In object-oriented programming, a way could be a programmed procedure that's defined as a part of a category and included in any object of that class. a category (and thus an object) can have over one method.
To invoke a way on an object is to ask it to perform an action. for instance, you will define a technique named get Area(), which you then may invoke to return a circle's area. instantiation. Creating an instance. Explanation: it's the simplest way of mixing both data members and member functions, which treat those data members, into one unit. We call it a category in OOP generally.
Method and function are the identical, with different terms. a way may be a procedure or function in object-oriented programming. A function may be a group of reusable code which may be called anywhere in your program.
