What else can I help you with?
Is NaCl most likely to dissolve in benzene a nonpolar solvent?
no
What substance is most likely to passively diffuse across the plasma membrane by dissolving in the membrane?
Nonpolar molecules like lipid-soluble substances (e.g., steroid hormones, oxygen, and carbon dioxide) are most likely to passively diffuse across the plasma membrane by dissolving in the lipid bilayer. This type of diffusion does not require a specific transport protein and can occur directly through the phospholipid bilayer due to the molecules' hydrophobic nature.
You have a spot of oil which is nonpolar on your favorite shirt.in which substance will the oil be most likely to dissolve?
The oil is nonpolar, so it will be more likely to dissolve in a nonpolar substance. Substances such as gasoline, kerosene, or other nonpolar solvents would be more effective at dissolving the oil spot on your shirt.
Where are you least likely to find water in the plasma membrane?
You are least likely to find water in the hydrophobic interior of the lipid bilayer of the plasma membrane. Water tends to be excluded from this region due to the hydrophobic interactions between the lipid molecules.
What are the bumps seen on the fractured surface of the membrane of a freeze-fractured bilayer?
The bumps seen on the fractured surface of a freeze-fractured bilayer are likely the lipid bilayer itself. When the bilayer is fractured, the hydrophobic interior of the membrane exposes lipid molecules, which appear as bumps on the fractured surface. Additionally, proteins embedded in the membrane can also contribute to the bumps seen on the fractured surface.
Is a hydrophobic molecule more likely to be polar or nonpolar?
A hydrophobic molecule is more likely to be nonpolar.
What molecule is most likely to enter a cell by simple diffusion through the lipid bi-layer?
Small, nonpolar molecules like oxygen, carbon dioxide, and water are most likely to enter a cell by simple diffusion through the lipid bilayer due to their ability to directly pass through the hydrophobic interior of the membrane without the need for facilitated transport.
Which of the following would likely move through the lipid bilayer of a plasma membrane most rapidly?
Small, nonpolar molecules such as oxygen and carbon dioxide would likely move through the lipid bilayer of a plasma membrane most rapidly due to their ability to dissolve in the hydrophobic core of the membrane.
Is NaCl most likely to dissolve in benzene a nonpolar solvent?
no
Is a dipole-dipole interaction more likely to occur in a polar or nonpolar molecule?
A dipole-dipole interaction is more likely to occur in a polar molecule rather than a nonpolar molecule.
What substance is most likely to passively diffuse across the plasma membrane by dissolving in the membrane?
Nonpolar molecules like lipid-soluble substances (e.g., steroid hormones, oxygen, and carbon dioxide) are most likely to passively diffuse across the plasma membrane by dissolving in the lipid bilayer. This type of diffusion does not require a specific transport protein and can occur directly through the phospholipid bilayer due to the molecules' hydrophobic nature.
Substance A is a Molecular compound that dissolves in gasoline but not water. The molecules of A are very likely....what?
Nonpolar. Molecules that dissolve in nonpolar solvents like gasoline tend to be nonpolar themselves, as nonpolar substances are attracted to each other through London dispersion forces. Water, being a polar solvent, is not able to dissolve nonpolar molecules as effectively.
What type of molecule would be likely to diffuse across the phospholipid bilayer of the cell membrane?
an ion
You have a spot of oil which is nonpolar on your favorite shirt.in which substance will the oil be most likely to dissolve?
The oil is nonpolar, so it will be more likely to dissolve in a nonpolar substance. Substances such as gasoline, kerosene, or other nonpolar solvents would be more effective at dissolving the oil spot on your shirt.

You are least likely to find water in the hydrophobic interior of the lipid bilayer of the plasma membrane. Water tends to be excluded from this region due to the hydrophobic interactions between the lipid molecules.
How can one determine if a bond is polar or nonpolar without relying on electronegativity?
One can determine if a bond is polar or nonpolar by looking at the symmetry of the molecule. If the molecule is symmetrical and the atoms on either side of the bond are the same, the bond is likely nonpolar. If the molecule is asymmetrical or the atoms on either side of the bond are different, the bond is likely polar.
Nonpolar solvents will most easily dissolve solids that are?
Nonpolar solvents will most easily dissolve solids that are also nonpolar or have weak polar interactions. This is because like dissolves like, meaning substances with similar polarities are more likely to mix together. Examples of nonpolar solids that dissolve well in nonpolar solvents are hydrocarbons like fats, oils, and grease.
