What is the correct pathway of oxygen as it travels from the lungs and goes to the cells of the body?

Explanation:

The correct pathway of oxygen as it travels from the lungs and goes to the cells of the body is: lungs, bronchioles, alveoli, capillaries, cells

Respiration begins at the nose or mouth, where oxygenated air is brought in before moving down the pharynx, larynx, and the trachea

The trachea branches into two bronchi, each leading into a lung

Each bronchus divides into smaller bronchi, and again into even smaller tubes called bronchioles, at the end of the bronchioles are air sacs called alveoli, and this is where gas exchange occurs

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.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
