Each foot is formed by three regions: 7 tarsals make up the ankle and heel, 5 metatarsals make up the sole of the foot, and 14 phalanges form the toes. Like the thumb, the big toe only has two bones, yet it is thicker than the other phalanges. Speculate on the reason.

this transfer is call conjunction

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.
