    Sorry guys and girls but I currently taking biology and I am not sure of the answer. If you could please help me and my grade would greatly appreciate it. 1) what happens to a plant cell's chloroplasts when placed in a hypertonic solution? 2)we used chromatogrpahy to seperate pigments on a paper. How do we know which is the most soluble in solvent? The one that went to the top? Which is least soluble? once again thank you for any and all help. (as you can tell, I am not a science major!)

    1) think about it, hypertonic gives away the answer
    2) Im pretty sure the explanation of how chromatography works will explain the one,

    Please open your textbook before posting here, this is not a homework forum.

    seriously? thanks. i am member of a couple of forum's and anytime that someone goes on and ask a question we try our best to answer it. we are not all science majors and/or have any interest in it. if you are ignorant enough to think that i would just come on a science forum to find an easy route you are incorrect. thanks robbie, i feel very welcomed.

    People would have tried their best to answer your question if it had seemed a question out of curiosity, or if you genuinely couldn't figure something out. When you post what looks very much like a homework assignment people are not going to be willing to answer you, nor should they.
