1.             glowing         
2.   (a)           fuel         
      (b)         oxygen         
      (c)  a sufficiently high temperature  (Any order)
3.   (a)           brown         
      (b)          dark blue        
4.   (a)           faster         
      (b)       carbon dioxide      
      (c)          oxygen         
5.             air sacs         

Short Question
(a)  Process X: photosynthesis                                                 
(b)  A: light energy  B: carbon dioxide  C: oxygen  D: water                      
(c)  Leaf has chlorophyll which can absorb the light energy (A) from the Sun.           

Long Question
(a)  Respiration                                                             
      Food + Oxygen à Carbon dioxide  + Water + Energy              
(b)  (i)    Intercostal muscles, ribs and diaphragm                                  
      (ii)   During breathing in, the intercostal muscles contracts, causing the ribs to move   
             upwards and outwards; at the same time, the diaphragm move downwards. Hence,
             the volume inside the chest increases, the gas pressure inside the chest decreases,  

             thus air is drawn into the lungs.

4.   (a)                 carbon dioxide                    
      (b)               greenhouse effect                  
5.   (a)                     Breathing                        
      (b)               gaseous exchange                  

Short Question
(a)  Heat energy is released in burning. When the burning French fries is place below the  
      boiling tube, water in the boiling tube absorbs heat, causing the rise in temperature of  
      the water.                                                              
(b)  Jason should compare the increase in water temperature per gram of French fries     
      used. The greater the increase in water temperature per gram of snack used, the      
      higher the energy content of French fries.                                    
(c)  Jason should weight the piece of French fries before heating it on a Bunsen burner.    


































(d) (i)    Extensive clearance of forest decreases the absorption of carbon dioxide in the   
              atmosphere.                                                        
      (ii)   Extensive burning of fuels increases the amount of carbon dioxide released to    
              the atmosphere.                                                      
      (iii)  These human activities increase amounts of carbon dioxide in the atmosphere.   
              This leads to an excessive greenhouse effect and hence global warming.         
      (iv)  There may be more cases of extreme weather conditions.                     
              The melting of ice in the polar region may speed up, leading to flooding in       
              low-lying areas. (or other reasonable answers)
