The answer is fatty acid.
Fatty acids are monomers of lipids. Fatty acids are not found in RNA.
By weight, almonds are about 50% fat. Of this fat, 90% consists of mono and polyunsaturated fatty acids. The main fatty acids in almonds are oleic acid and the omega-6 fatty acid linoleic acid.
Almonds are high in monounsaturated and polyunsaturated fats which have been linked to reduced risk of heart disease. However about 10 - 15% of the fat in almonds isn't absorbed by the body.
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.
