The correct answer is: Sodium and potassium ions move by active transport, and glucose moves by facilitated diffusion.
Because sodium and potassium are moved through cell membrane against their concentration gradients, transport requires energy (ATP), so it is active. <span>Glucose is a polar molecule and because the plasma membrane is impermeable to polar molecules transport of this important nutrient is accomplished by carrier proteins. This process is called facilitated diffusion and it is passive transport (doesn’t require energy).</span>
Potential and kinetic energy. Most object have kinetic energy. If an object is moving it is a kinectic energy. Potential energy is an energy stored in the position or arrangement of the object.
Answer:
Melting is the process where the atoms of a rigid solid Crystal lattice held by strong bonds, are broken down which increases the degree of locomotion of these atoms which characterises the liquid state.
The energy that breaks these bonds is heat energy ( latent heat of fusion ), hence temperature increases
Answer:
I think it is Physical change
