Answer: Biosynthesis is a multi-step, enzyme-catalyzed process where substrates are converted into more complex products in living organisms. In biosynthesis, simple compounds are modified, converted into other compounds, or joined together to form macromolecules. This process often consists of metabolic pathways.
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.

Answer:
Sunlight will not be properly absorbed
Explanation:
Plants rely heavily on sunlight to produce their own food through the process called photosynthesis. Photosynthesis occurs in leaves of plants because they contain most of the chlorophyll in the plant. Acid rain weakens the integrity of the plant by dissolving its waxy protective covering. So when the leaves get damaged, it limits their absorption of sunlight which is integral in the food making process of these plants. Limitations will cause a deficiency, or in other words, it will not be able to produce enough food for it to sustain its health.
