Answer:
C) They are compressed during inhalation.
Explanation:
Birds breathe through rigid lungs that are located in the animal's thoracic region. The trachea of birds divides into bronchi that branch inside the lungs into very thin tubes called parabronchials or parabroncholes, which are irrigated by blood capillaries that allow gas exchange.
In birds there are no pulmonary alveoli (as in mammals), but air capillaries that depart from the parabroncholes. Oxygen gas passes from these capillaries to the blood capillaries, thus causing gas exchange.
In the lower portion of the bird's trachea, before branching the bronchi, we can find the syringe, a bag-like structure that has vocal cords responsible for the birds' scream and song. Most of the time, the sound emitted by birds serves to attract the mate, mark territory and prevent birds of the same species against some predator or other danger.

Answer: Incomplete Dominance
Explanation:
Incomplete Dominance occurs when an heterozygous phenotype, different from the two parents homozygous phenotypes is expressed in the OFFSPRING.
FOR EXAMPLE: A pure breeding Red flower (RR) plant crossed with a pure breeding White flower (rr) plant and PRODUCES offspring with PINK flowers (Rr). This is Incomplete Dominance.
