- Cattle list said to cause change - Cause of change - Change-causing agent - Manipulating agent - Reaction agent - Reaction agents - Substance which produces chemical reaction without undergoing any permanent change
- Feedback concerning model in coat - Reflex movement - Reply - Respond to stimulus - Any action in resisting other action or force; counter
tendency; movement in a contrary direction; reverse action. - The mutual or reciprocal action of chemical agents upon
each other, or the action upon such chemical agents of some form of
energy, as heat, light, or electricity, resulting in a chemical change
in one or more of these agents, with the production of new compounds or
the manifestation of distinctive characters. See Blowpipe reaction,
Flame reaction, under Blowpipe, and Flame. - An action induced by vital resistance to some other
action; depression or exhaustion of vital force consequent on
overexertion or overstimulation; heightened activity and overaction
succeeding depression or shock.
- Dissolution; degeneration; decay. - A process by which reaction occurs in the presence of
certain agents which were formerly believed to exert an influence by
mere contact. It is now believed that such reactions are attended with
the formation of an intermediate compound or compounds, so that by
alternate composition and decomposition the agent is apparenty left
unchanged; as, the catalysis of making ether from alcohol by means of
sulphuric acid; or catalysis in the action of soluble ferments (as
diastase, or ptyalin) on starch. - The catalytic force.
