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.
Vitamin D plays a vital role in the regulation of calcium deposits and maintenance of the phosphorous levels in the blood which are two elements that are significantly important for maintaining healthy bones.

Answer:
Be used as source of reserve cells for the entire blood production system.
Explanation:
Stem cells can be described as special human cells that are capable of developing into many different cell types ranging from brain cells to muscle cells. They act like renewable source of replacement cells for treating diseases.
In this case, the proliferative potential and self-renewal of stem cells makes them a compensatory mechanism and reserve source for the entire hematopoietic system. While they could be of possible use in certain autoimmune conditions or in cases of organ failure, these statements do not capture their essence.
It should be noted that, hematopoietic system is the system comprising the organs that are involved in the production of components of blood. And this is the major reason why the couple should engage in the act after consulting the caregiver.
