Слайд 3: INTRODUCTION
The three basic types of adaptations, based on how the genetic changes are expressed, are structural, physiological and behavioral adaptations. Most organisms have combinations of all these types. What are some examples of adaptation? Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Other adaptations are behavioral. Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations.
Adaptation Definition. “ Adaptation is the physical or behavioural characteristic of an organism that helps an organism to survive better in the surrounding environment.” Living things are adapted to the habitat they live in. This is because they have special features that help them to survive.
Слайд 7: SPECIFIC ADAPTATIONS
What is adaptation ecology? All adaptations help organisms survive in their ecological niches.... Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats.
Слайд 8: SPECIFIC ADAPTATION
ADAPTATION IS A BIOLOGICAL MECHANISM BY WHICH ORGANISMS ADJUST TO NEW ENVIRONMENTS OR TO THE CHANGES IN CURRENT ENVIRONMENT IN EVOLUTIONARY THEORY, THE IDEA OF NATURAL SELECTION IS THAT TRAITSTHAT CAN BE PASSED DOWN ALLOW ORGANISMS TO ADAPT TO THE ENVIRONMENT BETTER THAN OTHER ORGANISMS OF SAME SPECIES
Слайд 10: SPECIFIC ADAPTATION
An adaptation is a characteristic of an organism that improves its chances of surviving and/or reproducing.... There are three different types of adaptations : Behavioural - responses made by an organism that help it to survive/reproduce. Physiological - a body process that helps an organism to survive/reproduce.
Слайд 12: SPECIFIC ADAPTATION
EXAMPLE: THE DOMINANT HAND OF A TENNIS PLAYER WILL HAVE LARGER BONES THAN OPPOSITE MARTIAL ARTISTS CAN TOUGHEN THEIR SHINS AND FOREARMS INTO STEEL WEAPONS THROUGH REPEATED SHOCK TREATMENT OF BONES PLACE OF HEEL BONE WHERE IT STRIKES THE GROUND, WILL BE VERY HARD AND DENSE
Слайд 14: What Makes This Adaptive Response Specific?
The general adaptive response is what occurs to the body when pretty much any system is stressed, hence the term “general adaptation”. Thus, this is the same process that makes you tan, the same process that builds callouses, and the same process that builds muscles. The body is not very good at understanding specificity.
