Dinitrophenol (DNP) is a metabolic poison that forms proton pores (holes large enough for H+ to pass) to be formed in the inner mitochondrial membrane allowing H+ to diffuse across the membrane. Why is DNP a poison?

Dinitrophenol is a yellow crystalline compound. It undergoes sublimation and is a high explosive when dry. It is a precursor to some chemicals and is well known for its inhibition of Adenosine Triphosphate(ATP) production in cells which contain mitochondrion. It is however a poison because of its high severe toxic nature due to its ability to increase metabolism at a very rapid pace and causes very high body temperature which is the main cause of death. This very high body temperature it causes affects the cardiovascular and nervous system of the body.

This made it to be banned for consumption and is used to make other products such as antiseptics, explosives etc.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
