In chemistry class, we learn the rule "like dissolves like" when studying why polar substances dissolve in each other (like sucrose in water) and why non-polar substances dissolve in each other (like fats in oil). Which of the following statements illustrates this rule?
a. Ribosomes are found inside of prokaryotic cells rather than outside.
b. Prokaryotes lack a nuclear membrane while eukaryotes have one.
c. More prokaryotic cells could fit inside a 1-cm cube than eukaryotic cells could.
d. Transmembrane proteins remain in the plasma membrane even though they are not attached to anything.
e. Chemical messengers or hormones bind tightly to their receptor proteins on the outside of a cell.
