What is soluble in a nonpolar substance?
Typically nonpolar substances are soluble in other nonpolar substances. Like disolves like...
What assists the movement of polar molecules across the membrane A. Passive Transport B. Active Transport?
Polar molecules must pass through the membrane via active transport. This is because the cellular membrane is mostly nonpolar, and polar and nonpolar molecules repel each other. Only nonpolar molecule (i.e. hormones) can pass through the membrane without active transportation.
How do you explain the phrase like dissolves like in terms of polar and nonpolar substances?
Polar substances dissolve other polar substances, and nonpolar substances dissolve other nonpolar substances. A polar substance cannot dissolve a polar substance and a nonpolar substance cannot dissolve a polar substance.
Which part of the cell membrane is nonpolar and prevent the cell from dissolving?
Nonpolar fatty acid chains are nonpolar and prevent the cell from dissolving.
Which molecules difuse through the lipid portion of the plasma membrane?
Only nonpolar (hydrophobic) molecules can pass through the bi-lipid membrane. For example, hormones are nonpolar, and they can pass through the membrane.

Why iodine is more soluble in cl but less soluble in water?
Iodine is not soluble in water because iodine is nonpolar and water is polar. According to the "Like dissolve like" expression, nonpolar substances are soluble with nonpolar substances and polar substances are soluble with polar substances, but nonpolar substances are not soluble with polar substances.
How do you explain the phrase like dissolves like in terms of polar and nonpolar substances?
Polar substances dissolve other polar substances, and nonpolar substances dissolve other nonpolar substances. A polar substance cannot dissolve a polar substance and a nonpolar substance cannot dissolve a polar substance.
Are polar and non polar liquids soluble?
Generally not. The general rule to go by is like dissolves like. Polar substance will dissolve other polar substances while nonpolar substances will dissolve other nonpolar substances.
What does like disslove like mean?
Polar substances dissolve in polar liquids. Nonpolar substances dissovle in nonpolar liqiuds. (For more info on polar and nonpolar, refer to Chemistry)

Does covalent substances conduct electricity in benzene?
Benzene is nonpolar and thus will only dissolve nonpolar substances. Covalent substances is vague, but even if benzene were to dissolve nonpolar solutes, they would not conduct electricity because the current has no ions or delocalized electrons to travel across.
How do nonpolar regions of a membrane proteins cause proteins to be held in the membrane?
IB sucks
What is nonpolar solvent?
For nonpolar substances, anything that is symmetrical is nonpolar, so something likeHexane (C6H12) or any other hydrocarbon would work.
What substances dissolve in oil?
Grease
