What structures of the cat urinary system are "retroperitoneal"?

The correct answer is kidneys.

The urinary system of cats consists of the kidneys which are located retroperitoneal (lie behind the peritoneum), the ureters (connect the kidneys to the bladder), the bladder, and the urethra (the tube through which urine exits the body). The functions of the urinary system are to excrete the waste products, to maintain the balance of water and electrolytes (salts) within the cells, to produce hormones erythropoietin and renin (maintaining blood pressure and producing blood cells).

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.
