For which of the following molecules does shape have an effect on its ability to carry oxygen? a. fat molecules b. dna c. origen d. hemoglobin

Correct D. Hemoglobin

The protein hemoglobin has four polypeptide chains, each one bound to a heme group. Each hemoglobin molecule can carry four oxygen molecules because of the presence of four heme groups. The binding of the first oxygen molecule modifies the shape of hemoglobin molecule slightly, this helps in increasing the oxygen binding capacity of the hemoglobin molecule. So, this alteration in shape increases the oxygen carrying capacity of the hemoglobin molecule.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.
