Answer:

<u><em>Galapagos finches</em></u><u> have various beak sizes that make foraging for food more successful.</u>

Explanation:

Organisms evolve over time due to changes in their genome. These are pontaneous, and occur in DNA at random. These changes are called mutations and form alleles or different forms of a gene.

Over time within a population, the number alleles increase the variation of the population. These variants may confer specific traits within an individual, that may confer a biological advantage.

Thus, the trait may make the organisms more capable of obtaining food, shelter a mate etc. or ensure survival, i.e. they are able to pass on their genes to the next generation.

The respiratory structure that contracts and relaxes to allow air to flow in and out of the lungs is the: Group of answer choice
ohaa [14]

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.
