I believe that a pair of homologous structures in this case is; Maple leaf and oak leaf. Homologous structures that have similar ancestries and common traits, however they may not have the same function in an organism. They appear in different animals or organisms, underlining anatomical commonalities demonstrating a descent from a common ancestor. Examples include the arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale.
Hyponatremia is a condition in which the levels of sodium in the blood is too low. Some of the symptoms of hyponatremia include headaches, muscle cramps or spasm, seizures, weakness, restlessness, and confusion. Hyponatremia can occur from excess fluid in the body, or a loss of sodium in body fluid.
