Dr. haxton told one of his students, "to move in the bloodstream, fats need the of phospholipids." what would a good student say?

Phospholipids refer to the molecules comprising hydrophobic lipid tails and hydrophilic phosphate heads. They are present in the cellular membranes and do an essential function by enveloping and safeguarding internal cellular constituents.  

In the given case, the student will say yes, as nonpolar molecules like fats are not compatible with water. The nonpolar molecules like fats get rejected by water, and thus, fats travel within the particles, which are enveloped with the polar parts of proteins and phospholipids.  

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.
