The answer is the first one: Protoporphyrin.

Explanation for each option:

  1. Protoporphyrin: This is the correct answer. Protoporphyrin is the organic component of the heme group in hemoglobin. It is a porphyrin ring that binds to an iron ion, which is essential for oxygen transport in the blood.

  2. Proline: This is incorrect. Proline is an amino acid, not related to the heme group structure in hemoglobin.

  3. Protozoa: This is incorrect. Protozoa are single-celled eukaryotic organisms, not related to the structure of hemoglobin.

  4. Porin: This is incorrect. Porins are proteins that form channels through cellular membranes, not related to the heme group in hemoglobin.

In summary, the organic portion of the heme group in hemoglobin is known as Protoporphyrin.

Decide whether each molecule or polyatomic ion is polar or nonpolar. If the molecule or polyatomic ion is polar, write the chemical symbol of the atom closest to the negative side. For example, if the molecule were HCl and you decided the hydrogen atom was closest to the negative side of the molecule, you'd enter "H" in the last column of the table. - molecule or polyatomic ion polar or nonpolar? atom closest to negative side - CH2O polar / nonpolar □ - CH3Cl polar / nonpolar □ - I2 polar / nonpolar □

Supply, Demand, and Market Equilibrium In supply (and demand) problems, N is the number of items the supplier will produce (or the public will buy) if the price of the item is x dollars. For a particular product: The supply equation is: N=2x+387 The demand equation is: N=-7x+558 Supply and demand lines intersect at the equilibrium price. This is the price at which there is neither a surplus nor shortage in the market (supply and demand are equal). Solve this system of equations to determine the point at which the two lines intersect. Give your answer as an ordered pair. The two lines intersect at the point: Write your answer as an ordered pair In this situation, what is the selling price when supply and demand are in equilibrium? When supply and demand are in equilibrium, the selling price per item is What is the number of items in the market when supply and demand are in equilibrium? There are items in the market when supply and demand are in equilibrium.
