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.
Conductors and Insulators. In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.Conductor implies that the outer electrons of the atoms are loosely bound and free to move through the material.Most atoms hold on to their electrons tightly and are insulators.onductor implies that the outer electrons of the atoms are loosely bound and free to move through the material. Most atoms hold on to their electrons tightly and are insulators.
