The Effect of Stimuli on the Behaviour of an Organism. Animals and plants react to stimuli (sing. stimulus) which may come from other living things or from the environment. A stimulus usually causes the organism which receives it to respond to it.Therefore the stimulus changes the behaviour of the organism in some way.he Effect of Stimuli on the Behaviour of an Organism.

Copper is soft and easily bent and so is a good conductor of electricity, which makes it useful for wiring. Copper is also a good conductor of heat and it does not react with water. This makes it useful for plumbing, and making pipes and tanks.
The metal in electric wire is called the conductor. Many materials are used to transmit electrical energy, but those most frequently used are copper, copper-covered steel, hâ¦igh strength copper alloys, and aluminum. i was thinking copper. Silver is the best electrical conductor but its cost prevents its use in ordinary wiring. copper is the next best, with aluminium third. For house wiring copper is almost uni â¦ versal. For overhead power lines aluminium is preferred for its lower density which reduces the cost of overhead lines significantly although slightly larger conductors must be used for a given amount of power.
