B. It's less dense. Ice floats<span> because it is about 9% less dense than liquid water.</span>
<em><u>Andesite:</u></em>
<em>Is an extrusive igneous, volcanic rock, of intermediate composition, with anphanitic to porphyritic texture. In a general sence, it is the intermediate type between basalt and decite and ranges from 57 to 63% silicon dioxide as illustrated inTAS diagrams.</em>
I think one is carbon dioxide not sure what the other is
Osmosis only talks about water molecules
Diffusion talks everything other then the water molecules.
So,
Osmosis : water molecules travel from a region of a higher water potential to a region of lower water potential through a partially permeable membrane via osmosis
Diffusion : Travels from a region of higher concentration to a region of lower concentration through a partially permeable membrane via diffusion
