Importance of Water in Chemical Evolution

Polarity = Water molecule with positive charge on one side and negative charge on the other side Hydrogen Bonds = Cause water molecules to cling to other water molecules Covalent Bonds = Form when atoms don't share electrons equally Chemical Evolution = Interactions between atoms and molecules in primordial seas

Intercellular fluids = Where water is stored in the body Extracellular fluids = Where water is stored in the body Sweat, urine, bowel movements = Ways water is lost from the body Primitive metabolism = Dependent on liquid water to operate

Water molecule = One oxygen atom and two hydrogen atoms Blood and organs = Store water in the body Atoms and molecules = Interact in primordial seas for chemical evolution Hydrogen atoms and oxygen atom = Components of a water molecule

<p>Breathing = One of the ways water is lost from the body Digestion = One of the ways water is lost from the body Water molecules structure = Consists of one oxygen atom and two hydrogen atoms Chemical reactions = Enabled by water suspending and dissolving molecules</p> Signup and view all the answers

<p>Polar covalent bonds = Make water an asymmetrical molecule with positive and negative charges Hydrogen bonds = Cause water molecules to flow as a unit Liquid water = Needed for primitive metabolism to operate Organisms on land = Carried water inside their cells when they moved to land</p> Signup and view all the answers
