Mr. Turner, my American history teacher, taught us about the U.S. home front during WWII. Enjoy!
It can become a sedimentary rock over time because of weathering. sedimentary rocks are rocks that have been broken down over time by water and erosion. hope this helps.
I. Facilitated diffusion is your answer.
Active transport <span>is the movement of molecules across a cell membrane into a region of higher concentration, this process requires energy. Both osmosis and diffusion are passive transportations which means that they don't require energy.
Hope this helps!

<span>Sclerenchyma cells are the strongest. They have a second cell wallwhich is hardened by lignin, making them very tough and durable.</span>
<span>The correct answer:
copper is important in the synthesis of collagen.</span>
Copper activates an enzyme called lysyl oxidase that's required for collagen maturation.Lysyl oxidase catalyzes the formation of aldehydes from lysine residues in collagen and this results in cross-linking collagen (stabilization of collagen fibrils).
