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.
Gold is a very good conductor of electricity. It is often used as plating for connectors because it does not tarnish or corrode... Gold is a very good conductor of electricity. It is often used as plating for connectors because it does not tarnish or corrode easily. Even though copper and silver are better conductors than gold, gold retains its conductivity longest because it does not tarnish or corrode easily. For this reason, gold is most often used in plating where it is exposed to the air.
