Tmp/smx has two components that act on different steps in the folic acid biosynthesis pathway and are thus used together. sulfamethoxazole is a structural analog of a compound called paba, competing with it in the enzymatic production of dihydrofolic acid, an intermediate in the synthesis of folic acid. trimethoprim inhibits the step following dihydrofolic acid production and prevents the formation of the biologically active form of folic acid. choose true statements regarding tmp and smx.
Trimethoprim-sulfamethoxazole (TMP-SMX) are a class of antibiotics used in the treatment of bacterial infections due to their inhibitory actions in the folic acid biosynthesis pathway of bacteria.
What is TMP-SMX?Trimethoprim-sulfamethoxazole (TMP-SMX), otherwise known as co-trimoxazole, is a combination of two antimicrobial agents that work synergistically to inhibit the enzyme systems involved in the bacterial synthesis of tetrahydrofolic acid.
They are used in the treatment of urinary tract infections, respiratory tract infections, cholera, etc.
They can be administered intravenously or orally.
Therefore, Trimethoprim-sulfamethoxazole (TMP-SMX) are antibiotics used in the treatment of bacterial infections.

The weathering that most likely played the largest role in creating the cliff was when water in the river broke down the rocks into smaller pieces, which is present in Option B.
What is the weathering process?Rock cliffs can be formed by a variety of weathering processes. One common process is erosion caused by the movement of water as seen here as water flows through the mountains. Over time, these agents of erosion can wear away the softer layers of rock, leaving behind the harder layers that form the cliffs. Physical weathering is caused by the action of natural forces such as water, wind, etc. For example, water can flow into cracks in rock and then freeze and expand when the temperature drops, causing the rock to break apart. Wind can also erode rock surfaces over time by carrying small particles of sand and other debris that scrape and wear down the rock.
Hence, here the largest role in creating the cliff was when water in the river broke down the rocks into smaller pieces, which is present in Option B.
