Asurge in which hormone(s) immediately precedes ovulation? a surge in which hormone(s) immediately precedes ovulation? progesterone only fsh only lh and fsh lh only

The answer is LH only. Luteinising hormone promotes the release of an egg from an ovary during ovulation. Follicle Stimulating Hormone, on the other hand,  stimulates the maturation of ovarian follicles. When its levels drop and LH surge, ovulation of a mature egg from the mature follicle occurs.  

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.
