How do neutral solutes move across the plasma membrane? Can the polar molecules also move across it in the same way? If not, then how are these transported across the membrane?

In co-transport across membrane:

Assertion : proteins are called as pumps in active transport. Reason : they use energy to carry substances across cell membrane .

Two sound waves moves in the same direction in the same medium. The pressure amplutides of the waves are equal but the wavelength of the first wave is double the second. Let the average power transmitted across a cross section by the first wave be P_1 and that by the second wave be P_2 then.

Which is the electric potential difference across the plasma membrane of a resting neuron?

Name the three filtration barriers that solutes must come across as they move from plasma to the lumen of Bowman's capsule. What components of the blood are usually excluded by these layers?

Which of the following statement are correct? (i) Cell membranes allow water and non polar molecular to prmeate by simple diffusion. (ii)Polar molecules like amino acids can also diffuse through membrane. (iii)Smallermolecules diffuse faster than larger molecules. (iv)Larger molecules diffuse faster than smaller molecules.
