11. Who suggested that peppered moths were an example of natural selection?
weeeeeb [17]

Answer:

J. W. Tutt suggested that peppered moths were an example of natural selection.

Explanation: Before industrial revolution, the population of white peppered moth is high as compared to dark peppered moth because white peppered moth can't be seen at night by the birds. After industrial revolution, sooth is spread on the surface of the trees which make easy for the bird to see white peppered moth and feeds on them. Population of white peppered moth decreases while the population of dark peppered moth increased because they cannot be seen in the dark due to black color of sooth.

Which of the following does not characterize the lungs of birds?
kompoz [17]

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.
