i hope that you're thinking about hormones.
as for actual messengers, there's about a thousand of which we have names for about a hundred.
1. Pure natural gas (CH) doesn't smell. 2. Smell is a chemical property of substances because is caused by specific molecules.
The chemical name for natural gas is methane (CH4).
It is CH4, otherwise known as methane.
Natural fertilizers are derived from organic materials such as compost, manure, or bone meal, while chemical fertilizers are synthetically manufactured with specific concentrations of nutrients. Natural fertilizers provide slow-release nutrients and improve soil structure, while chemical fertilizers deliver nutrients quickly but can harm beneficial soil organisms if overused. Many farmers and gardeners prefer natural fertilizers for their sustainability and long-term soil health benefits.
The burning of natural gas is a chemical property because it involves a chemical reaction. When natural gas (methane) reacts with oxygen in the air, it produces carbon dioxide, water, and heat energy. This is a chemical change as new substances are formed.
Introduction of and support for natural predators and use of botanical and chemical controls are ways to treat lime trees for aphids. Treatment by natural enemies focuses upon such voracious aphid-eaters as ladybugs and syrphid flies. Botanical controls include horticultural oils against eggs and insecticidal soaps against immature and mature stages whereas chemical controls at their eco-friendliest list as active ingredients pyrethroids.
Nobody controls a tornado; it is a natural event.

It depends on what specific part. Or what object is wearing but generally it is called weathering or erosion. Weathering can be either chemical or natural. ;)

Those that have the resources
Aeolus controls the winds.
A chemical compoud or a chemical reaction are not forces.
Pr is the chemical symbol of the natural chemical element praseodymium.
It is with the preferential use of chemicals over non-chemical controls that non-organic food is grown.Specifically, organically grown food is produced in adherence to specific ways of producing edibles. Its production opts for biological and natural treatments, with strong emphases upon the well-being of the plant in question but also of the soil in which it grows and the soil food web with which its roots share space underground. In contrast, non-organically grown food tends to be produced with attention to regular fertilization schedules -- which emphasize nitrogen, phosphorus and potassium over other nutrient needs -- and non-natural controls, such as chemical, conventional, synthetic pesticides.
Yes, combustion of natural gas is a form of chemical change.
