Which is the order of airflow during inhalation?
Brums [2.3K]

The correct answer is B. Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli

Explanation

The breath of living beings is divided into two processes, the first is inhalation and the second is exhalation. Regarding the first, it is the process in which the air is taken by the beings to be conducted to their lungs through their noses, passing through the nasal cavity, larynx, trachea, bronchi, bronchioles and finally alveoli where gas exchange occurs. The second process is the opposite, in which the air inside the lungs converted into CO2 is expelled, passing through the same places in an inverted manner, that is, alveoli, bronchioles, bronchi, trachea, larynx and nasal cavity. So, the correct answer is B. Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli.

Which of these best describes genetic drift? A) The movement of alleles between population B) Random fluctuations in the gene fr
exis [7]
The correct answer is B.
Genetic drift is one of the four evolutionary mechanisms. It changes the frequency by chance, aka at random.
For example. if you have 100 frogs in the population, 20 red, 20 green and 60 yellow, not all of the alleles are going to be passed down to the next generation because a portion of the population can be affected by a random event such as the flood. So, if the flood accidentally kills 20 red frogs, none of the offspring are going to be red by chance.
