It stretches through from the Nile River in Egypt to the Tigris and Euphrates rivers in modern Iraq. It also encompasses several other countries, including Israel, Lebanon, Jordan and Syria.
January 1950 is the answer I’m pretty sure:)
They have both hydrophilic and hydrophobic regions.
<h3>
Why can lipids pass through the cell membrane easily?</h3>
Permeability refers to the ease with which molecules cross biological membranes. Because of the chemical and structural nature of the phospholipid bilayer (hydrophobic core), only lipid-soluble molecules and some small molecules are able to freely pass through the lipid bilayer.
<h3>
What materials can easily diffuse through the lipid bilayer and why?</h3>
The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
