Ducklings follow their mother due to imprinting.
Answer:
The answer would be Hydrophobic tail and a hydrophilic head. Just some background info, this is located in the cell membrane and the cell membrane is made of up something called the Lipid Bilayer. The word "bi" means 2, so it comprise of 2 layers of phospholipids. These 2 layers of phospholipids are called hyrodrohpbic and hydrophilic. The word "phobic" means fear, so they hydrophobic molecules are NOT attracted to water. Hydrophilic molecules, however, ARE attracted to the molecules.
Hope this helps!
they do not bare together
The answer is C. lipid membrane
The reason for this is, as stated in your question, it is called a phospholipid bilayer.
It's called like that because it is made out of lipids and it also has phosphate groups, while the bilayer part means it just has two layers. Therefore it is commonly also called a lipid membrane.
