Sharp-edged beak best describes the mouth of a turtle.

Option D

Explanation:

The mouth of a turtle has sharp edged beak in both the sides of the upper and lower jaw. The muscle of the jaw is so strong that it can amputate your finger when it bites.

The mouth has sharp papillae which looks as sharp thorns protruding throughout the esophagus till the stomach. This aids to get a hold on their meals like jelly fish which are generally slippery to eat without grip. It also protects them from their poisonous sting.The papillae contains thick proteins similar to our fingernails.

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.
