A. As the pan of the water is heated, the water molecules moves faster and father apart.
As the water is heated, the water molecules gains more kinetic energy as the result of the heat that is been added by the stove. The gained kinetic energy allows the molecules to move faster and to move father away from one another.
b. If there are more water inside the pan, the same phenomenon experienced in the [a] above will still occur, but this time around it will take a longer period for the reaction to occur. This is because, there are more water particles in the pan and therefore it will take longer time before the heat from the stove circulate round all the particles.
Answer:
The leak channels allow Na+ and K+ to move across the cell membrane down their gradients (from a high concentration toward a lower concentration). With the combined ion pumping and leakage of ions, the cell can maintain a stable resting membrane potential.
Hope this helps!
Explanation:
Bacteria cells have no what? They have no nucleus.
They first 'cut out' genes using precise biological 'scissors' – restriction enzymes – and paste them into DNA from another organism like a bacterium or yeast where it is copied many thousands or millions of times. Molecular model of a restriction enzyme bound to DNA.
