How do biological organisms use energy worksheet answer key?

Organisms use energy in two steps:

Organisms harness the chemical energy of the food and convert it into more usable for that is, ATP. The set of chemical reactions involved in this process is termed as cellular respiration. It may include glycolysis, Krebs cycle, electron transport chain, oxidative phosphorylation.

Organisms use the energy associated with ATP through a hydrolysis reaction. The hydrolysis of ATP releases ADP, Pi,  and energy. ADP is further hydrolyzed to produce AMP, Pi, and energy.

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.
