Answer:
1: 7.8 cm
2: .7 cm
3: 5.55 cm
For the other questions, you have to use a ruler yourself and measure using cm. :) 
1 cm = 10 millimeter. To convert, just add a 0 to the end of cm to find the mm (or move the decimal one place to the right.) 
For example, 2.6 cm = 26 mm / 5 cm = 50 mm. Hope this helps!
 
        
             
        
        
        
I would say A or C I’m not sure but if I had to choose A or C my best guess would be A 
I hope this helps :)
        
                    
             
        
        
        
<u>Answer:</u>
Carbon is found in hydrosphere in the form of dissolved carbon in ocean and sea water during the gas exchange process. 
<u>Explanation:</u>
- Carbon cycle is the process of transformation of carbon in different forms. From atmosphere, the carbon gets into hydrosphere during the gas exchange processes. 
- During this gas exchange process, the carbon is dissolved in the ocean water which is later utilized by marine plants to conduct photosynthesis. 
- There is a continuous transformation of carbon from lands, plants to atmosphere and from atmosphere to hydrosphere.
