what is a ground block

Ground tissue is a major component of the stem. It is undifferentiated. The ground tissue is represented by several layers of loosely arranged parenchyma cells enclosing prominent intercellular spaces. The ground tissue is meant for storage of foo..

Underground reservoirs of fresh water are called aquifers. They are continuously recharged through infiltration, sewage and evapo transpiration. The total volume of ground water found in the aquifer is estimated to be 42.3 x 10 1 0 m ..

). Total upward pull is 4 x 1000 or 4000 N with an effort of 1000 N [Figure (c) above] In practice owing to the weight of the lower block and the friction between the pulley and the rope, the effort E needed to raise a load of 4000 N is more than 1000 N, say 1200 N. Figure shown below ill..

How many blocks will there be in the next figure of the pattern? => 32 or 64 or 128 or 256..

Choose the number of pattern blocks. => 6 or 7 or 5 or 8..

Which number is shown by the blocks? => 350 or 35 or 3,150 or 315..

Introduction - The elements that lie in between S-block and P-block are the d-block elements. These elements are called transition elements as they show transitional properties between s and p-block elements. These elements contain partially filled d-orbitals..

Introduction - The long form of the periodic table is based upon the filling of a particular shell and has been accordingly divided into four blocks i.e. 's', 'p', 'd' and 'f' blocks. The 's' block elements involve the filling of 's' subshell. This block incl..

Which number is shown by the blocks? => 1,065 or 1,506 or 1,605 or 1,560..
