For the answer to the question above, <span>Muscles can only contract, not push </span>

<span>"Muscle fiber generates tension through the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten or remain the same. Though the term 'contraction' implies shortening, when referring to the muscular system it means muscle fibers generating tension with the help of motor neurons (the terms twitch tension, twitch force, and fiber contraction are also used)."</span>

How are the terms nucleotide, nitrogenous base, and nucleic acid related to each other?
hoa [83]

A nucleic acid is made of nucleotides, and nitrogenous bases are a part of a nucleotide.


DNA is a nucleic acid.  The nucleotides in DNA are made up of a sugar (deoxyribose), a phosphate group, and one nitrogenous base (which will be either adenine, guanine, cytosine, or thymine).


Hope this helps!!
