Embryo sac , and other three degenerate !
Atmospheric Fixation. The enormous energy of lightningbreaks nitrogen molecules and enables their atoms to combine with oxygen in the air forming huge nitrogen oxides. These dissolve in rain, forming nitrates, that are carried to the earth.
The answer is convergent plate boundaries. Convergent of two plates depends on the types of crust that are colliding. Convergence can take place between two slabs of continental lithosphere, two slabs of oceanic lithosphere or between one continental and one oceanic slab. Oftenly when two plates collide one or both are destroyed nd when oceanic crust converges with continental crust the denser oceanic plate plunges beneath the continental plate.
Answer: The concentration of the cytoplasm of red blood cells will be 0.5m.
Explanation: Red blood cells that are bathed in blood neither shrink nor swell and burst because the concentration of the surrounding blood is equal to the concentration inside the cytoplasm of the red blood cells. This means that the two solutions are isotonic. Since the two solutions are isotonic, there will not be movement of water molecules across the red blood cell membrane. Osmosis do not occur between two solutions of equal concentration, for osmosis to occur water molecules must move from a region of high water concentration to a region of low water concentration through a selectively permeable membrane.
