Which element on the periodic table is known as the "foundation" element for molecules in living things?
Carbon
What type of covalent bond is water?
Polar
True or false: How elements interact with one another depends on how their electrons are arranged and how many openings for electrons exist at the outermost region where electrons are present in an atom.
Biomolecule which is responsible for providing energy for most organism.
Carbohydrates
______ is the process of turning the food we eat into energy?
Digestion
Why are Lipids hydrophobic (Water-fearing)?
