The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules: A molecule in the bulk liquid experiences cohesive forces with other molecules in all directions. A molecule at the surface of a liquid experiences only net inward cohesive forces.
        
             
        
        
        
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.
