ANSWER: vA Feedback: Because vcell vmembranes vare vsoluble vto vsome vlipid-soluble vsubstances vsuch vas vorganic vsolvents, vsuch vsubstances vshould vbe vkept vfrom vdirect vcontact vwith vskin vcells. vThe vfacts vthat vcell vmembranes vhave va vhydrophilic vhead vand va vhydrophobic vtail vand vcontain vreceptors vfor vhormones vand vbiologicallyvactive vsubstances vdo vnot vhave vavbearing von vthe vnurse's vteaching. vWhile vtransmembrane vproteins vcan vindeed vpass vinto vthe vintracellular venvironment, vthe vnurse vis vnot vreferring vto vproteins vin vthe vteaching.
