It is called a joint. Joints are also called articulations, they are strong connections that join the bones, teeth, and cartilage of the body to one another. Each joint is specialized in its shape and structural components to control the range of motion between the parts that it connects. Joint is usually formed of fibrous connective tissue and cartilage, they may be grouped according to the type of motion: ball and socket joint, hinge joint, condyloid joint, which permits all forms of angular movement except axial rotation, pivot joint, gliding joint, or saddle joint.
To see the difference between <span>biped and a quadruped,</span> let's compare the skeletons of the man (biped) and the horse (quadruped):
*The man has the bigger pelvis: he has to bear the weight of the body.*The scapula is smaller.*The bones of the hind leg bigger.*The forearms more mobile.*The man has the spine that attaches under the skull.*And the tail that has completely regressed.
the man has adapted to standing and biped (he walks on 2 feet): his hind legs are reinforced.

Answer:
By preventing the synthesis of DNA halting cell growth.
Explanation:
Fluorouracil and methotraxate prevent the synthesis of the neucleoside Thymidine thus preventing DNA replication and elongation. Methotraxate has a structure analogous to Folic acid which is important for thymidine synthesis. Thus, it acts as a competitive inhibitor on dihdrofolate reductase an enzyme that is essential for tetrahydrofolate formation, a folic acid derivative.
Fluorouracil acts by inhibiting thymidylate synthase which catalyses an essential step in Thymidine synthesis.
