The embryo sac contains two cells- one with two haploid nuclei and one that will be fertilized. What happens to the cell with two haploid nuclei? A. This develops into a new pollen grain to fertilize another seed.

B. It will combine with a haploid spore and become the nourishment in the seed.

C. The other cell degenerates into the plant.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
