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.
The correct answer should be Carrying capacity
Carrying capacity is the the number of people, animals, and other life forms, that an ecosystem can sustain without starting to degrade, and all these upsets can destroy it because it can cause people and animals to migrate somewhere or they can destroy the carrying capacity of the already existing one.
