Answer: Relatively less abundant water on land makes survival difficult for terrestrial animals. All four problems stem from a lack of water. Terrestrial animals spend energy looking for water, which is not available easily. Terrestrial temperature fluctuates widely, so energy investments have to be made to keep body temperatures regulated.
Explanation:
Of the four globins that make up hemoglobin, two are identical and called alpha globins, and the other two are called beta globins and are also identical.
<h3>Structure of Haemoglobin</h3>
- Each of the four subunits of hemoglobin has a polypeptide chain and a heme group.
- The iron protoporphyrin IX prosthetic heme group, which is connected to a polypeptide chain with residues of 141 (alpha) and 146 (beta) amino acids, is present in all hemoglobins.
- A histidine's N is linked to the ferrous iron of the heme. A polypeptide chain phenylalanine of the porphyrin ring wedges it into its pocket.
- Alpha and beta chains, two varieties of the polypeptide chains that make up adult hemoglobin, are comparable in length but have different amino acid sequences.
- Both adult and embryonic human hemoglobins have the same alpha chain.
