The steps for the formation of the enzyme pepsinogen in the correct order is as 1, 4, 2, 3.
Pepsinogen is a chemical that is created by the cells that exist in the stomach. During digestion, pepsinogen is converted into pepsin by the acid in the stomach, and pepsin is responsible for breaking down the proteins in food. The formation steps are as;
Step 1: The DNA strands unwind, and RNA polymerase binds to the template strand.
Step 2: The synthesis of mRNA begins. The amino acids assemble to form peptide.
Step 3: The mRNA undergoes intron splicing and exits the nucleus.
Step 4: The tRNA moves through mRNA with the activated amino acids attached to it.
The complete question is attached.

Answer:
b . chemical weathering
Explanation:
Chemical weathering is not affected the flow of groundwater through an aquifer but affect by the porosity and permeability. The rate of groundwater flow is controlled by two properties of the rock which are porosity and permeability. Porosity is the percentage of void space in a rock while on the other hand, Permeability is the quality of being permeable means able to be penetrated or passed through by a liquid or gas.
