Cell membranes are mostly made up of lipids (fats)
<span>The answer is b. have a change in dipole moment
When a molecule absorbs an infrared ray, its energy will increase. The energy will increase the rotational movement or the molecule. If the energy increases further, it will become the vibrational movement. Dipole moment will be increased if the vibrational movement is increased.</span>
Explanation:
The air pressure will decrease because the air particles are spread out.
That why hot air always travel upwards
Answer: It is approximately the membrane potential at which the electrochemical gradient for Na+ is zero.
Explanation:
The charge in plasma membrane occurs with diffusion and electric fields.
For example, if there are two solutions, let's assume solution X and Solution Y are separated by a porous barrier (to diffuse in equal proportions).
The fundamental principle of diffusion states that solution from a high concentration diffuses to a lower concentration.
For instance, if the X solution contains 40 sodium ions and 40 chloride ions, the Y solution only has 30 sodium and 30 chloride ions. Due to the diffusion, these two solutions will mix and reach a steady-state.
The like charges repel, and opposite charges attract.
