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:
The correct option is e
Explanation:
An inversion mutation is a situation in which a sequence of the gene on a chromosome breaks out and rearranges itself from reverse (to the beginning) and then attaches itself back to the point of breakage of the same chromosome.
From the question, mutation changed the gene sequence from ABC*DEFGH to ABC*DGFEH. From this mutation, it can be seen that the gene sequence "EFG" broke-out, rearranged itself from reverse to the beginning as "GFE" and then attached itself back to the points of breakage.
NOTE: This type of inversion is called paracentric inversion since the centromere (represented as * in the question) is not part of the breakage.
The correct answer is (d.) proteins. Higher organisms use nitrogen to make their protein. Food that is containing protein also involves nitrogen in it. Protein also has amino acids that contain nitrogen in it which is a necessary essential nutrient for the body.
velocity= distance / time
your distance is 180 miles
your time is 3 hours
180 divided by 3 = 60
