1. Some animals learn not to react to a stimulus if, after many repeats, it proves to be harmless. This is called dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural.

2. Habituation prevents the animal wasting time and dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural on needless repeats of its dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural response.

3. Habituation only brings about a dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural modification of the escape response, otherwise the animal would be left open to dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural.

4. In advanced animals, learning involves a dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural modification of the response made to a stimulus. Information is stored in the central nervous system and dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural for future use.

5. Animals show many dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural defence mechanisms such as dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural and protective coverings.

6. dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural mechanisms for defence are found amongst animals which remain together in a protective dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural.

7. Some plants possess dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural adaptations for defence such as thorns and dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural.

8. The dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural form of some plants enables them to tolerate dangerenergygrazinggroupgrowthhabituationindividuallong-termrememberedshort-termSocialspinesstructural animals.
