If we name the gene for freckles with F, then the genotypes for having freckles are Ff (heterozygous), FF (dominant homozygous) and for no freckles ff (recessive homozygous).

If we name the gene for nose shape with N, than the genotypes for broad noses are NN (dominant homozygous) and Nn (heterozygous) and for narrow noses nn (recessive homozygous). A cross between two heterozygous:

P: FfNn  x  FfNn

F1:

9/16 are with freckles and broad noses

3/16 are with freckles and narrow noses

3/16 are with no freckles and broad noses

1/16 are with no freckles and narrow noses.

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.
