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.

Answer:
C.
Explanation:
Traits would not make them more likely to survive than their parents because the parents also had the same traits. It would affect the children because they would be as likely as their parents to survive in thay environment, but would not necessarily adapt if the environment changes because the trait would have to evolve.
Answer:
"Fitness" from a biological perspective would mean the ability of a person's muscles and organs to perform tasks and functions at high levels.

A.
The mitochondria is the site of the aerobic respiration in the eukaryotic organism. The mitochondria uses the glucose and the oxygen molecules to form the carbon dioxide, water and ATP (adenosine triphosphate) molecule.
The equation for the aerobic respiration is given below:
Glucose + oxygencarbon dioxide + water
All the reaction takes place in the mitochondria, Hence, the givenb lanks can be filled as follows:
1. glucose
2. oxygen
3. carbon dioxide
4. water
5. ATP
B.
The process shown in the figure is aerobic respiration. In the given figure, the mitochondria is shown, the mitochondria is the site of aerobic respiration. The mitochondria obtain the glucose and the oxygen molecule present in the cytoplasm of the cell. The complete aerobic respiration takes place in three steps glycolysis, Kreb cycle and electron transport. In the glycolysis, the glucose is converted into pyruvate. In the Krebs cycle, the pyruvate is oxidised in acetyl-CoA, which undergoes a sequence of reaction giving out ATP from ADP. In the electron transport chain, the NADH as well as succinate, which is formed in the citric acid cycle or Krebs cycle are oxidized, which provides the energy to power ATP synthase (the enzyme involved in the creation of storage of ATP).
