Rocks at the surface of the Earth are of many different ages, ranging from over 3 billion years old to less than 1 million years old. Because under ordinary circumstance matter can neither be created or destroyed, the new, younger rocks must have originated from the older crustal material - older rocks. Older rocks are destroyed by weathering processes and the remains are recycled into new rocks<span>. This cycle from old rocks to new rocks is called the </span><span>rock cycle.</span>
Answer:
The ecological system theory explains about the interaction of the child's development with the surrounding environment. It describes different layers of interaction:
1. the microsystem: this is the closest layer of child's surrounding. This layer includes the interaction of the child with family, school, neighbourhood and childcare environment. This layer results in bi-directional influence on the belief and behaviour of child from parent and vice versa.
2. the mesosystem: this layer is the interaction of between child's microsystems. Example interaction of child's teacher with parents.
3. the exosystem: in this layer the child has no active role. In this behaviour of the child is influenced by parents working shedule and community based interactions.
4. the macrosystem: this is the outermost layer of child's interaction with the environment. This mainly includes customs, law and culture which a child follows. It is the chief responsibility of parents how a child perform these functions. So, the child's actions are influenced.
5. the chronosystem: this layer describes the physiological changes occurs in a child with respect to time.
This theory mainly focuses on the physical, cognitive and psychological changes in the child with relation to the different environmental layers. This theory only focuses on the physical and social environment. Does not included the interior barrier responsible for the overall development like parents education, low income, geographic mobility which can have an influence on child's health. I completely agree with this critics.
Answer:
it provides energy for conversion of ADP to ATP by ATP synthase. Anabolic pathways store energy by building molecules
Explanation:
Catabolic pathways release energy by breaking down molecules. ... Hydrogen ion generation is essential for ATP production because it provides energy for conversion of ADP to ATP by ATP synthase.
Tubercle: allows production of red blood cells
Foramen: allows smooth gliding of bones.
Tossa: allows tendons to attach to bone.
