Answer:
The correct answer is C. continued education
Explanation:
Education is important for both low and high-income countries for the prevention of disease in their people like HIV, tuberculosis. School education is very much important which provide information about the infectious and non-infectious disease to the children.
Educating children about the prevention of these diseases is important because school children are at the greatest risk of getting STDs. Education is one of the most cost-effective ways to prevent HIV, tuberculosis and other diseases. Therefore the correct answer is C. continued education.
 
        
             
        
        
        
Answer:
The correct answer would be option D.
I statement would not be a valid response as it is the fact on which the conclusion was made.
On the conclusion provided, one should ask about the cell type used in the study and the amount of chemicals those cells were exposed to.
Different types of cells may response in different manner against a particular chemical. For example, stem cell would response in different manner whereas differentiated cell would response in different manner.
Similarly, the amount or concentration of chemical plays important role in any reaction or cellular response. For example, the affinity of haemoglobin is high towards oxygen in alveoli whereas it is high towards carbon dioxide in body cell. 
So, the correct answer would be option D.
 
        
                    
             
        
        
        
Answer:
When a mustard plant seedling is transferred to an environment with higher levels of carbon dioxide, the new leaves have a lower stomata-to-surface-area ratio, it is because the concentration of carbondioxide is high in the surrounding environment so the plant produce small leaves having less number of stomata. If the concentration of carbondioxide is lower so big leaves are produced having maximum number of stomata.

<span>A biogeochemical cycle is the process of transport and cyclic transformation of a chemical element (like oxygen, carbon or azote) or a compound between the large reservoirs that are the geosphere, the atmosphere, the hydrosphere, in which the biosphere is found.
</span>The three elements are able to exist in a gaseous form in the atmosphere to complete their respective natural cycle.</span>
