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.

Reptile [31]
PP-  purple homozygote
pp- white homozygote
Pp- purple hetrozygote

If these flowers cross, we obtain heterozygote offsprings with a genotype: Pp (100% of them will be like this)

Now, if those offsprings cross with each other: Pp x Pp
results:
  1/4 would be purple  homozygote -> PP
  1/4 would be white -> pp
  2/4 would be purple heterozygotes -> Pp
Genotipic ratio: 3:1 (3 are purple; 1 is white)
