The correct option is (A). Are found in Plasma membrane
Phospholipids are the major constituent of the plasma membrane.
<h3>
What are phospholipids' primary purposes?</h3>
- The primary component of the plasma membrane is phospholipids. They are made up of fatty acid chains joined to a glycerol or other similar backbone, just like fats.
- The glycerol backbone's third carbon is bonded to a phosphate group, hence there are only two fatty acids connected as opposed to three.
- An alcohol is added to the phosphate group to change it. Both hydrophilic and hydrophobic areas can be found in phospholipids. While the phosphate is hydrophilic and interacts with water, the fatty acid chains are hydrophobic and keep themselves away from it.
- A membrane with a bilayer of phospholipids surrounds each cell. The phosphate group can face either the outside environment or the inside of the cell, both of which are watery, as opposed to the fatty acids of phospholipids, which face within, away from water.

The diaphragm is the large dome-shaped muscle that rests right under the lungs and separates the abdominal cavity from the thoracic cavity. The contractions of the diaphragm are what truly facilitate the movement of air in and out of the lungs. The contraction of the diaphragm, or breathing in, leaves more room in the chest cavity for the lungs to expand as the diaphragm "tightens". The expanded lungs are filled with oxygen-rich air which is then is diffused through capillaries to different parts of the body. The process of breathing out occurs when the diaphragm relaxes, slowly resuming its position its original position in the chest cavity. When relaxing, carbon dioxide is forced out of the lungs.

Answer: A compound is a substance in which two or more elements are combined together chemically.
Explanation: Elements present in a compound are always in a fixed proportion and can be separated only by a chemical method. For example, water is a compound composed of hydrogen and oxygen atoms in the ratio of 2:1. The chemical formula of water is H2O.
<span>The absence of the predator in the experimental plots led to a rise in population of the two species hence suppressing the other species since they were the prey of the Sea stars. But when the sea stars were present, they maintained a balance in the species diversity by feeding on Mussel and Barnacle species.</span>
It is called ecological succession, which can take up to a decade. It is a process of change in the species structure that occurs after a vast loss or extinction. Ecologists study how complexity is evident when a community is formed or occurrence takes place from an empty land or bare soil.
