The respiratory structure that contracts and relaxes to allow air to flow in and out of the lungs is option(c) i.e, the diaphragm.

<h3>What is the diaphragm?</h3>

The diaphragm, a delicate skeletal muscle that separates the chest from the belly, is located at the base of the chest. When you breathe in, it flattens and shrinks. As a result, the lungs experience a vacuum effect that draws air in. The diaphragm relaxes and the air is forced out of the lungs when you exhale.

signs of diaphragm issues:

  • Acid reflux, heartburn, coughing, and difficulty swallowing.
  • alterations to skin tone (skin may turn blue).
  • rapid heartbeat, pressure in the chest, and/or breathing difficulties (especially when lying down).
  • Headaches.
  • Hiccups that persist or recur frequently.

Patients who need surgery for conditions affecting the chest, including diaphragm issues, are treated by a thoracic surgeon.

Relate the development of plant needles to the occurrence of mutations.
xxMikexx [17]
<h2>Development of Plant Needles</h2>

Explanation:

  • Seed of pitch pine treated with colchicine delivered tetraploid seedlings which had thick and sporadic needles and less fortunate tallness and diameter growth than ordinary seedlings.  
  • In test of colchicine-initiated polyploidy in pines, researcher found that a significant number of the polyploid plants returned to a diploid development in light of the fact that the polyploid cells partitioned at a more slow rate and were overwhelmed by the more quickly developing diploid cells which encompassed them.  
  • The primary needles of both diploid and polyploid plants were more effective at low light intensity than secondary needles, and they had lower compensation points.
