Acting as levers for movement is a function of: bones.
Movement can be defined as a process through which several skeletal muscles in the body systems act together as a group, in order to cause a change in the motion of a body part.
Basically, bodily movement are produced when skeletal muscles exerts a force on the tendons, which in turn pull on the bones (levers) and other supporting structures such as the skin.
In the body of living organisms, bones act as levers for movement by enhancing limb speed or power of limb movements while joints act as a fixed point of movement (fulcrum).

Answer:
Early land animals had both lungs AND gills, and their bodies consisted of few hard parts. Meaning they lacked things like an exoskeleton for instance. Animals today have either lungs OR gills and many have protecting hard parts of their bodies.
Explanation:
Answer:
the formation of new cells for the replacement and repair of old cells as well as for growth.
Explanation:
Answer:
It recognizes and binds to a pair of "mismatched" nucleotides, preventing their translation.
Explanation:
Mut L protein is involved in mismatch DNA repair. MutL protein is complexed with MutS protein and the MutL-MutS complex recognizes all the mismatched base pairs present in the newly formed DNA strand. The complex can not recognize the "C-C" pairs. MutH protein joins the complex.
The MutH protein also has a site-specific endonuclease activity and cleaves the unmethylated DNA strand towards the 5' end of the guanine base in the GATC sequence to mark the strand for DNA repair. In this way, MutL protein, along with MutS and MutH proteins mark the mismatched DNA bases for repair so that they are not translated into a faulty protein.
Answer:
DNA polymerases
Explanation:
The formation of a phosphodiester bond between adjacent nucleotides is catalyzed by the DNA polymerases. They do this efficiently only if the incoming base on the incoming nucleoside triphosphate is complementary to the base on the template strand and can bind efficiently.
