Phospholipids are found in plasma membranes. are water-soluble. contain subunits called amino acids. are fat-soluble vitamins. a
KengaRu [80]

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 part of the eye that prevent light from reflecting internally and is heavily vascularized to deliver blood to the retina:___
Ne4ueva [31]

The part of the eye that prevent light from reflecting internally and is heavily vascularized to deliver blood to the retina: choroid.

<h3>What is choroid?</h3>

The choroid is highly vascularized to provide blood to the retina and contains dark pigmentation to stop light from reflecting inside. Anteriorly, the choroid, ciliary body, and iris are all joined.. The ciliary body muscles regulate the lens's thickness. The iris acts as a diaphragm, changing the pupil's aperture at its center. This regulates how much light is allowed to enter the retina. In strong light, the iris' muscle fibers constrict the pupil to accommodate close vision; in low light, they enlarge it to accommodate far vision. Each individual's iris is a different color.
