Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion.
Contraction is the answer
Mountain slopes have faster erosion because it is easier for fast moving bodies of water to carry down eroded material downhill, rather than across flat land.
Answer:
The valence electrons have a role in the bonding of two atoms. The nuclei of each atom are drawn together by their attraction to the valence electrons of the other atom. As the atoms are drawn together by their attractions, electrons from each atom are drawn to the nuclei of both atoms, where they are "shared."
