    Soldier313 Jaf take the second dotted line from the bottom (first x) as the zero level. since the pressure acting on that level in both the columns is the same, and the liquid does not level off in each of the bars in the u tube. so 1x of Q exerts the same pressure as 2x of P. so ρ = P / gh ρ...

    In the scenario given, each of the springs extents by x, and each gets a share of 1/3 W (F) so put it in the equation F = kx, itll be 1/3F = k x k = F/3x (this will be the k for all the springs since they are the same) now in the next case....the remove one spring and double the W so now each...

    remember in the stem the xylem is inside and the phloem outside in the root, the xylem is inside (star shaped) and phloem outside in the leaf the xylem is on the top and phloem on the bottom in this question, firstly the palisade is the upper layer is fatter in C and D, so throw away A and...

    remember this... Ψ = Ψs + Ψp and the pressure potential is always positive so X is pressure potential now looking at the equation we know water potential is always negative, but solute potential has to be even more negative, cuz the pressure potential will be added to it, therefore Z is solute...

    Nuclear division is a general term, basically the dividing of the nucleus. It can either be my mitosis or meiosis (reduction division)

    oops my bad, semi conservative replication has nothing to do with mitosis, it occurs in the interphase..

    1) when mitosis occurs the daughter cells are smaller than the parent cell, they grow in the inter phase, so 2 and 3 are right only. 2) D are the xylem cells, thick walls..and on the inner side... C are neither phloem nor xylem they are just there for division A are the cells in the pith and...

    heres the experiment.....the pictures are from the mary jones book..... so Meselson and his buddy decided to prove the SEMI CONSERVATIVE REPLICATION. they used E coli (you dont need to know what they grew and what nitrogen source they provided)....just know there are two isotopes of Nitrogen a...
