What best describes the association between the carbon cycle, plants, and animals? A)Plants fix carbon and release oxygen, and animals release carbon and use oxygen.

B) Animals fix carbon and release oxygen, and plants release carbon and use oxygen.

C)Animals fix carbon through respiration, and plants fix carbon through photosynthesis.

D)Plants decompose fixing carbon, and animals decompose releasing carbon.

A) Plants fix carbon and release oxygen, and animals release carbon and use oxygen.

Explanation:

Plants take in carbon dioxide and release oxygen into the air. The animals take in oxygen and release carbon dioxide.

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.
