Because it is harder to get the sugars out of complex carbohydrates and easier to get sugars out of simple sugars hence the name. 
        
             
        
        
        
Answer:
Friedrich Miescher discovered nucleic acids in blood cells.
Nuclein was discovered by Friedrich Miescher in 1869
Explanation 
In the somewhat early 1880s Albert Kossel further purified the substance and discovered its highly acidic properties. Then he later discovered the nucleobases. In 1889 Richard Altman creates the term nucleic acid. Friedrich Miescher was the first scientist to ever isolate nucleic acid.
 
        
                    
             
        
        
        
Answer:
The adaptations of desert plants to prevent water loss are small, modified leaves, a thick waxy cuticle, water storage capability, and dormancy during
 
        
             
        
        
        
It is also possible to move substances across membranes against their concentration gradient (from areas of low concentration to areas of high concentration). ... If the energy of ATP is directly used to pump molecules against their concentration gradient, the transport is called primary active transport.
Hope this helps 
 
        
             
        
        
        
Answer:
C)Both proteins bind ATP and F-actin
*C option is not mentioned* there is a flaw in the question
Explanation:
Two families of motor proteins, kinesin and dynein, transport membrane-bounded vesicles, proteins, and organelles along microtubules. Nearly all kinesins move cargo toward the (+) end of microtubules (anterograde transport), whereas dyneins transport cargo toward the (−) end (retrograde transport).While
both the protiens have globular ATP-binding heads that function as the motor domain and interact with the microtubules.
