Several species of finch live on the Galapagos Islands. They are very similar in appearance but have adapted beaks of different sizes and shapes based on their major food source. Finches with large beaks eat mainly large seeds and cacti. Finches with small beaks eat mainly small seeds and insects. Which of the following best explains the variety of beaks found in finches on the Galapagos Islands?

air, water, heat and noise pollution can all be caused by producing and using technology. consuming resources - non-renewable resources, including precious metals like gold, are used to make technology

the answer will be a) proteins i believe

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.
