Is the lipid bilayer permeable to most water-soluble substances?
The lipid bilayer is impermeable to most water-soluble substances.The bilayer, most of which is a phospholipid bilayer, is permeable only to small, non-polar substances.In nature, the most common compounds to pass through the bilayer are carbon dioxide and oxygen.Scientists differ over how much water passes in and out of cells through the bilayer; some passes through special transport proteins called aquaporins.

Molecules A and B come in contact with the cell membrane of the same cell Molecule A passes through the cell membrane readilybut molecule B does not Which statement could describe molecules A an?
Molecule A is likely smaller and more hydrophobic, allowing it to pass through the cell membrane easily via simple diffusion. Molecule B may be larger, polar, or charged, requiring a transporter or channel for passage across the cell membrane.
Molecules A and B are both organic molecules found in many cells when tested it is found that molecule A cannot pass through a cell membrane but molecule B easily passes through state one way the two?
Molecule A may be too large or too polar to pass through the cell membrane effectively, while molecule B may be smaller and more nonpolar allowing it to pass through easily via diffusion. The difference in membrane permeability between the two molecules could be due to variations in size, charge, polarity, or interaction with membrane proteins.
How does oxygen cross the cell membrane?
Air is inhaled into the lungs, where oxygen in the air encounters the hemoglobin molecule inside red blood cells, which has the capacity to form a weak attachment to the oxygen, so that oxygen can be easily picked up but also easily released, somewhat in the way that a sponge can pick up or release water. The red blood cells then move through the circulatory system of the body, pumped by the heart, and they arrive in due course in the smallest blood vessels, the capillaries, which have very thin walls. As the red blood cells are giving off oxygen, some of that oxygen will seep out through the thin capillary walls and will then encounter other cells of the body, and can pass through cell membranes by means of osmosis, thus entering the cell.

How do sounds travel through materials?
Sound is a vibration. It passes on energy from one molecule to another.

What passes through the plasma membrane by way of diffusion?
Small, non-polar molecules such as oxygen, carbon dioxide, and lipid-soluble substances can pass through the plasma membrane by diffusion. Water can also move through the membrane via a special type of diffusion called osmosis.
