the energy source is primarily the sun, and it drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil.
The boundary between conducting zone and respiratory zone structures occurs at the terminal bronchiole/respiratory bronchiole junction. The major respiratory structures span the nasal cavity to the diaphragm. Functionally, the respiratory system can be divided into a conducting zone and a respiratory zone. The conducting zone of the respiratory system includes the organs and structures not directly involved in gas exchange. The gas exchange occurs in the respiratory zone.
Answer:
C
Explanation:
In the cloning media, not all bacteria will take up the plasmid but some will. Including the antibiotic resistance gene allows the researcher to be able to select the bacteria that take up the plasmid (which are of interest to her because they will now bear the cloned gene). To select these cloned bacteria she puts ampicillin into the medium after some time. The bacteria that took up the plasmid, which also bore the antibiotic resistance gene, will survive and can be reproduced to give more bacteria population with the introduced human gene.
Some proteins lowers the activation energy of a reaction, making it more likely to proceed. The reaction will occur thousands or millions of times faster. The name of this special type of protein is enzyme.
Color change is the answer because that is a physical change
