Tails of the phospholipids in the phospholipid bilayer are hydrophobic, consisting of fatty acid chains.
<span>Phospholipids are composed of two fatty acids, glycerol and phosphate groups, forming an amphipathic molecule. Amphipathic molecules are built from hydrophilic (water-loving) and hydrophobic (not attracted to water) molecules. The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer. Hydrophobic molecules (fatty acids) are on the interior of the membrane, whereas the water-loving heads (phosphate head) point outwards, toward either the cytoplasm or the fluid that surrounds the cell. The head group and fatty acids are attached <span>to </span>a glycerol unit.</span>
Where is the claim for the answer
Hello,
Cinder Cone Volcanoes usually make up of Lava. These volcanoes are made of lava, not ash. Do not get that mistaken.
- I.A. -
Transmission electron microscope produces the image through a beam of electrons. It is most useful to inspect the morphology, cyrstallization, and magnetic characteristics of a certain sample.
I hope I was able to help you with your question. Have a good day.
I believe the answer is D.
