Por lo tanto, la proporción de ADN no codificante aumenta con el tamaño del genoma más rápidamente en las no bacterias que en las bacterias. Esto es consistente con el hecho de que la mayor parte del ADN nuclear eucariota no codifica genes, mientras que la mayoría de genes procariotas, virales y orgánulos sí lo son.
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.

<u>Answer</u>:
The two molecules generated by the Krebs cycle that pass their high-energy electrons to the electron transport are NADH and FADH2
<u>Explanation:</u>
The kreb's cycle gives NADH and also the another hydrogen carrier which is termed as FADH2. During the process of the electron transport chain, one NADH gives rise to electrons and also the hydrogen ions, which has enough potential energy that can convert and produce 3 ATP molecules. Again in the electron transport chain the NADH and the FADH2 undergoes oxidation and releases energy in the form of the ATP. The process of generation of the ATP in the electron transport chain(ETC) is also referred as the chemiosmotic phosphorolation.
