Answer:
Peacock with larger tails are most likely to produce more progeny.
Explanation:
Sexual selection is a type of natural selection wherein individuals with some specific genetic traits are preferred as a mate for interbreeding by the individuals of the opposite gender of the same species. For instance, in some species, males with large size have a greater chance to mate and pass on their genes to the progeny. This results in an increased frequency of the genes for the larger body size in population over time. Therefore, sexual selection results in the reproductive advantage for some individuals over others of the same species and sex.
In the given example, a peacock with larger tails is preferred as a mate by peahens and is able to produce more offspring. Due to its reproductive advantage, larger tails in peacocks are not selected against by natural selection.
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.
