Which of the following statements about passive transport is correct?
1) passive transport operates independently of diffusion.
2)passive transport operates independently of the concentrations of the
substance being transported.
3) in passive transport, all movement of the transported molecule stops when
its concentration is the same on both sides of the membrane.
4) passive transport does not occur in the human body.
5) passive transport permits the transported molecule to move in either
direction, but the majority of transport occurs down the concentration
gradient of the molecule.

Answer;

5) Passive transport permits the transported molecule to move in either

direction, but the majority of transport occurs down the concentration

gradient of the molecule.

Explanation;Passive Transport is the diffusion of a substance across a biological membrane without expenditure of energy by the cell.Examples of passive transport include; diffusion and osmosis. Diffusion is the simplest type of passive transport which involves the movement of molecules from an area of high to low concentration and leads to equilibrium.Osmosis on the other hand is the process by which water molecules diffuse across a cell membrane from high to low concentration. passive transport of water.Active transport unlike passive transport involves the movement of a substance across a membrane against its concentration gradient with the help of energy.

4, two dominant and two recessive

That is false even though water expands when frozen nothing changes at all
