The textbook Would most likely have more gravitational potential energy because it is heavier. Things that are heavier have a larger gravitational pull and are pulled to the earth faster
        
             
        
        
        
Hey there!
Speed and velocity both:
1) Measure how fast something is moving
2) Both measured in miles per hour, meters/second, etc (rates)
However, there's a prime difference:
Different because:
1) Velocity is speed, but in a certain direction
2) Velocity is a vector
3) Velocity can be positive <em>or</em> negative, unlike speed.
I added another just in case you had a preference :)
Hope this helps!
        
             
        
        
        
Answer:
Nucleotides
Explanation:
Nucleotides are the organic molecules which serve as monomer units for the formation of nucleic acid polymers which are the deoxyribonucleic acid and the ribonucleic acid (RNA) and both are the essential biomolecules within the life on the Earth.
Nucleotides are building blocks of the nucleic acids. They are the molecules which are composed of three sub units which are:  
- Nitrogenous base which is also called as nucleobase
- Five-carbon sugar  which can be ribose or deoxyribose
- At least one phosphate group which is attached to the sugar.
