Which of the following is a plausible pathogenic scenario? choose the correct answer from the following choices, and then select the submit answer button. a mutation that prevents the addition of co2 to the terminal amino group of the β chain leads to increased affinity of hemoglobin for o2, resulting in acute hypoxia. a mutation that eliminates the activity of an enzyme involved in porphyrin synthesis leads to increased anemia. a mutation that allows normal fetal hemoglobin to continue being produced into adulthood would enhance symptoms of sickle-cell disease. all of these scenarios are plausible. only the second and third scenarios are plausible.

The correct answer is option - only second and third scenarios are plausible.

Explanation:

A mutation that removes or eliminates the activity of the enzyme that is responsible or involved in synthesis of the porphyrin which cause pathogenic condition called anemia.

A mutation that allows that cause normal fetal hemoglobin to keep on producing into adulthood would enhances symptoms of sickle cell that is also a pathogenic condition.

Thus, the correct answer is option - only second and third scenarios are plausible.
