Describe the path that air takes as it enters and passes through the human respiratory system.
BabaBlast [244]

Answer:

In our respiratory system, there is a pair of external nostril situated above the upper lip that receives atmospheric air and passed to the pharynx (a common passage for air and food). The pharynx passed this air to the trachea via larynx (known as the soundbox). The trachea is an extended part which is divided into left and right primary bronchi. Bronchi divide into secondary bronchi, tertiary bronchi, and bronchioles that ending up in thin terminal bronchioles. Each terminal bronchiole constitutes a number of irregular-walled, thin and vascularised bag-like structures called alveoli which are the primary sites of gases exchange.

. According to the concept of entropy, what will likely happen to most molecules over time? (Points : 3) . -They will break down
emmasim [6.3K]
The correct answer is this: THEY WILL BREAK DOWN.
In chemistry, entropy is defined as the degree of disorderliness or randomness of a system. Entropy has to do with the second law of thermodynamic, which relates to how energy spread out. The entropy of a system can be positive or negative depending on the direction of flow of energy. In positive entropy, the degree of disorderliness increases while in negative entropy the degree of randomness decreases. A positive entropy will always leads to the breakdown of the affected molecules.
