    For the growth of amoeba I put that the growth will be decreased because since they're single celled, their cells won't get sugars and assimilates (from phloem) since vascular tissues aren't there.. IDKKK

    I got F A D E
    The correct answer would have been the fluctuating pressure rather than high pressure in arteries close to the heart as reason for the elastic tissue. Not sure what letter it was though

    I am fairly certain that that is very wrong :/
    Why's that? It makes sense that it was cut in the middle of the septum

    because the atria are definitely longer than that, and there is no mass of muscle separating the atria and ventricles.

    I did the same thing, was this for the fill in the caps ? hopefully allow it :/

    Nice, I put guard cells and mesophyll cells, no idea what's correct. What feature of the membrane doesn't allow minerals through? Seemed basic but I'm pretty sure I messed it up- phospholipid bilayer?
