Explanation:

Talk of evolution research most often conjures up images Darwin's finches.  The Stickleback fish, an animal model that can exhibit evolutionary changes in as few as ten generations, allows scientists to direct a more modern study of evolution.  Specifically, scientists are able to identify DNA changes that control skeletal adaptations in wild populations of sticklebacks through a serie s of simple experiments that would surely thrill even Darwin himself.

a range of structures from a simplified girdle with no pelvic spines to an oval nub

for a girdle.

no pelvic girdle and no pelvic spines.

sadness is not good

explanation:

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.
