Answer:
What is the main advantage to using satellites to measure climate change?
Explanation:
 answer A...Satellites in a low earth orbit can directly monitor the climate from their position within or just above the atmosphere, and can provide near-global coverage as they scan over different swathes of ground with each orbit.
 
        
                    
             
        
        
        
Answer:
By preventing the synthesis of DNA halting cell growth. 
Explanation:
Fluorouracil and methotraxate prevent the synthesis of the neucleoside Thymidine thus preventing DNA replication and elongation. Methotraxate has a structure analogous to Folic acid which is important for thymidine synthesis. Thus, it acts as a competitive inhibitor on dihdrofolate reductase an enzyme that is essential for tetrahydrofolate formation, a folic acid derivative. 
Fluorouracil acts by inhibiting thymidylate synthase which catalyses an essential step in Thymidine synthesis.

<span>The answer is letter D. all of the above. A cell may be represented in different models such as an idea model, a physical model and even a computer model. A cell in physical model may be a larger or smaller physical model that picture outs the parts of a cell, while in an idea model, a cell may be given analysis and descriptions and lastly, on a computer model, a cell may look animated or realistic depending on its graphical representation.</span>
