The term "hydrophillic" literally means water loving.
Hydrophillic substances are those that have an affinity of water, meaning they are easily dissolved and absorbed in water. Polar substances, those which have charges on the atoms of their molecules, tend to be hydrophillic due to the fact that water itself is a polar substance.
I believe the correct answer is homeostasis.
A long carbon and hydrogen chain and a carboxyl group.
In images of fatty acids (the monomers of Lipids), it is depicted as a long carbon chain with hydrogen on the ends and connected to them as well, yet on the clear side is the carboxyl group.
Hope this helps!
