It occurs by the process of breathing! The diaphragm expands and allows air into the lungs. This air is carries into your wind pipe, and in the tiny air sacs called aveiolli that are in your lungs. These aveiolli are connected to capillaries that then send carbon dioxide out throw the wind pipe yet again, and also spread the oxygen collected throughout the body.
Hope this helps! : )
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:
One pattern is that the A binds with T ans C with G for the DNA. The DNA transcription starts with the binding of the enzyme RNA polymerase to the promoter. The RNA then begins transcribing in data using one strand of DNA as the template. Thymine is replaced with uracil. To cleave the strand, the bacteria can use a termination step.
Does that answer your question? I hope so.
