The demand is elastic when the price is low. So people will buy more good so that it's demand will become more elastic. Moreover ,the demand is elastic when there are some new inventions.
Smoking affects your circilatory system badly. It clogs up your bronchioles and should not be done. This causes your bronchioles to become irritated and makes you cough to try to release it. This then affects your breathing some.

A bronchus is a passage of airway in the respiratory tract that conducts air into the lungs. The bronchus branches into smaller tubes, which in turn become bronchioles.
The airways and tissues of the respiratory tract, including the alveoli, become less elastic and more rigid; the chest wall becomes more rigid as well.
No, it's the other way around where the breach of condition can become a breach of warranty.
Support structures change: irregular plates of cartilage replace the cartilage rings, and by the time the bronchioles are reached, the tube walls no longer contain supportive cartilage. Epithelium type changes: the mucosal epithelium things as it changes from pseudostratified columnar to columnar and then to cuboidal in the terminal bronchioles. Mucus-producing cells and cilia are sparse in the bronchioles. For this reason, most airborn debris found at or below the level of the bronchioles must be removed by macrophages in the alveoli. Amount of smooth muscle increases: the relative amount of smooth muscle in the tube walls increases as the passageways become smaller. A complete layer of circular smooth muscle in the bronchioles and the lack of supporting cartilage (which would hinder construction) allows the bronchioles to provide substantial resistance to air passage.
These are called alveoli.The bronchi (or air passages) continually divide into smaller and smaller bronchi in the lungs, until they become bronchioles. The very smallest of the bronchioles end in a tiny sac or 'balloon' called alveoli.The alveoli are surrounded by a dense network of capillaries which allows the exchange of gases between the lungs and the bloodstream.alveoli
