Answer:
D giardiasis is the correct answer :)
Answer:
Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli.
Explanation:
The air travels through the respiratory system during inhalation in the next order:
- <em><u>Nasal cavity:</u></em> You inhale air into your nose.
- <u><em>Larynx:</em></u> The air travels down to this organ, a hollow, tubular structure that plays a key role in phonation, respiration, and deglutition.
- <u><em>Trachea:</em></u> (Or <em>windpipe</em>) is a wide, hollow and cartilaginous tube that connects the larynx to the bronchi.
- <em><u>Bronchi:</u></em> The trachea divides into two primary bronchi; they are the main passageway into the lungs.
- <em><u>Bronchioles: </u></em>The bronchi develop smaller the closer they get to the lung tissue and are then consider bronchioles.
- <em><u>Alveoli:</u></em> They are tiny air sacs located at the end of the bronchioles, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
Natural selection is the process that result in the adaptation of an organism to environment by means of selectively reproducing changes in its genotype, or genetic constitution. It is the a key mechanism of evolution. Charles Darwin popularised the term "natural selection" contrasting it with artificial selection, which is intentional, whereas natural selection is not.
To make it simple, let's have a group of beetle composing of green and some are brown as an example. here, there is a variation in traits. Since the environment could not support continuous population growth, not all species can reproduce to their full potential. Green beetles can easily be eaten by other species like birds compared to brown beetles. The surviving brown beetles will then generate brown offsprings because their trait has a genetic basis. Since more brown beetles survive and becomes more common in the population, the process continues until all individuals will eventually be brown. so basically, if you have variation, differential reproduction, and heredity, you will have evolution by natural selection as an outcome.
