During cellular respiration, OXYGEN serves as an electron acceptor and Adenosine triphosphate (ATP) is produced. during photosynthesis, WATER serves as an electron donor and oxygen molecules, hydrogen ions and electrons are produced.
Tight hydrogen bonding
The atoms in a compound are held together by a chemical bond. The chemical bonds can be either covalent bonds or ionic bonds. Both the bonds are considered very strong bonds. These bonds are mainly formed by sharing of electrons or in the case when one of the elements making the compound donates electron to the other element. The nucleus of each atom attracts to form a strong bond. This property of attraction between the nucleus of the atoms actually helps in forming the chemical bonds.<span>

A hypothesis is something that you predict and a theory is something that is capable of becoming true
Explanation:
Temperature is the amount of heat energy contained in the air, and we measure this in degrees. Air pressure is the amount of pressure exerted by the air in a particular air mass. Humidity is a measure of the water content of the air mass. Clouds are tiny drops of water or ice that form in the atmosphere.
Some molecules are too big they cannot diffuse through the membrane, for example starch (glucose) molecules.
