Why are the beak size and shapes of darwin's finches different?

C) They adapted to the type of food available.

Explanation:

The beak sizes and shapes of Darwin's fiches are different because of survival of the fittest. The finches that had beaks that could get the food survived while the other died off. Thus, the number of those survived finches increased while the others decreased. The type of food available in each environment is different from the other, which is why they have different sizes and shapes.

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.
