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!
 
        
             
        
        
        
Answer:
A. stratified squamous epithelium; absorption
Explanation:
Stratified squamous epithelium are composed of multiple layers of cells which rest on a basement membrane. Superficial layers are made of squamous cells and underlying layers can also be made of cuboidal or columnar cells. 
Stratified squamous epithelium  is generally present in area where there is frequent physical or chemical abrasion. It protects the underlying structures from the stress. Hence, it is found wherever the body comes in contact with the outer environment like skin, digestive system and respiratory system. It also prevents water loss and desiccation. 
 
        
             
        
        
        
Because the chain will begin to shut down and will no longer pump [H+] (hydrogen ions) across the membrane; thus, the proton gradient can not be maintained. 
:) I hope this answers your question!
