Pheromones are signaling molecules that trigger a specific response in members of the same species. They play a role in various behaviors such as mating, territory marking, and alarm signaling.
enthalpy
Chemical energy is stored in the bonds between atoms and molecules within a substance. When these bonds are broken through a chemical reaction, the stored energy is released.
Chemical energy is the energy stored in a substance due to its chemical composition. This energy is released when chemical reactions occur.
Chemical potential energy is the energy stored in the chemical bonds of a substance that can be released during a chemical reaction.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
Pheromones are chemical signals released by an organism to influence the behavior of others of the same species. Hormones are chemical substances produced by glands in the body that regulate various physiological processes. Pheromones are used for communication between individuals, while hormones regulate internal functions within an organism.
because it contains bi-carbonate, a substance that is released by an organism's saliva to quell heart burn.
neurotransmitter
Chemical energy is a form of potential energy stored within the chemical bonds of a substance. When chemical reactions occur, this energy can be released in the form of heat or light. It is a type of energy that is associated with the breaking and forming of chemical bonds.
