Lucky has learned a trick that not every dog is able to do. In other ways, Lucky is like all other dogs.
Identify some of Lucky's adaptations, as well as some variations among the population of dogs.

(This was based on a lesson about adaptations and variations

He is able to do tricks.

Hope that helps!

im not in connections yet but i might can you some questions. what grade are you in?

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.
