Isabella asked the doctor how matteo had managed to survive so far if blood was not properly circulating to his lungs. what structure was allowing some oxygenated blood access to the systemic circuit, thus keeping matteo alive immediately after birth?

pulmonary veins carries oxygenated blood and it is the structure that allows access to systemic circuit

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.
