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.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

i think its white blood cells

i hope this
