Which feature of a cell membrane determines whether molecules can cross the membrane?
They must either be lipid soluble (e.g. steroids) or very small (e.g. ions).
What does the difference in the K and Na concentration on either side of the plasma membrane and permeability of the membrane to those ions generate?
The difference in concentration of K+ and Na+ across the plasma membrane, along with the membrane's permeability to these ions, generates the resting membrane potential. This potential is essential for maintaining electrical excitability in cells, such as neurons and muscle cells, and is involved in processes like nerve signaling and muscle contraction.
If the membrane in a beaker were impermeable would the concentration of salt parts on either side of the mnrame change?
If the membrane in a beaker were impermeable the concentration of salt parts on either side will not change
What is osmotic change?
Osmotic change refers to the movement of water across a membrane in response to differences in solute concentration on either side of the membrane. This process is driven by osmosis, where water flows from an area of low solute concentration to an area of high solute concentration to equalize the concentration on both sides of the membrane. Osmotic changes can affect the volume and pressure of cells and organisms.
When there are different amounts of a substance on either side of the cell membrane an gradient results?
osmosis

Resting membrane Potential

How does osmosis explain the movement of water across cell membranes?
Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. In the context of cell membranes, water moves through the membrane to balance the concentration of solutes inside and outside the cell. This process helps regulate the cell's internal environment and maintain cell hydration.
What three conditions are needed for osmosis to occur?
Three conditions are needed for osmosis to occur: a semipermeable membrane that allows only water molecules to pass through, a difference in solute concentration on either side of the membrane, and a gradient in water concentration across the membrane.

Osmosis is a type of diffusion?
Osmosis is a special type of diffusion that involves the movement of water molecules across a selectively permeable membrane. It occurs when there is a difference in solute concentration on either side of the membrane, resulting in the movement of water to balance the concentration gradient.

osmosis
In diffiusion movement of particles across a membrane is drven by what differences?
In diffusion, movement of particles across a membrane is driven by differences in concentration gradients, which is the difference in concentration of a substance on either side of the membrane. Particles naturally move from areas of higher concentration to areas of lower concentration until equilibrium is reached.
How does humidity affect osmosis?
Humidity can affect osmosis by influencing the rate at which water molecules move across a semi-permeable membrane. Higher humidity levels can slow down the rate of osmosis by reducing the concentration gradient between the solutions on either side of the membrane. Conversely, lower humidity levels can speed up osmosis by creating a greater concentration gradient.
How do you describe osmosis?
Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a selectively permeable membrane. This process helps to balance the concentration of solutes on either side of the membrane.
Why is the concentration of oxygen on either side of the double membrane of a chloroplast different?
