Answer:
This might not sound like much, but the pH scale is logarithmic, so this ... The ocean absorbs about 30% of the carbon dioxide (CO2) that is released in the atmosphere. As levels of atmospheric CO2 increase from human activity such as burning ... track and forecast ocean acidification, warming and other important ocean

Answer:
The false statement is The iron in both the hemoglobin and myoglobin has two coordination sites that bind to oxygen.
Explanation:
Hemoglobin is an oligomeric,allosteric,conjugated protein with 4 polypeptide chains joined by non covalent bonds that contain heme prosthetic group.It is an iron containing porphyrin derivative present in all vertebrate.
The tetramers of hemoglobin consists of numerous combinations of seven polypeptide chains and each of which is encoded by separate genes.
Myoglobin is a globular protein that consists of single polypeptide chain of 153 amino acid residue and a single heme group.
Globin of Mb binds with single heme group by forming co ordinate bond.The heterocyclic ring system of heme is a porphyrin derivative.It is made up of 4 pyrrole ring and 4 pyrroles are linked by methine bridges to form a tetrapyrolle ring.
The Fe atom is present either in Fe²⁺ state or Fe³⁺ oxidation state in the center of protoporphyrin IX ring.The iron atom has 6 co ordination bond,4 in the plane of flat porphyrin ring and two perpendicular to it.
Actually, all four of them are correct. Bacteria are responsible for all of them and they are very important.
The obligate halophile halobacterium salinarum maintains a high intracellular concentration of this substance to prevent osmotic shock?
What is osmotic pressure?
Its common way to express the concentration of a solution. Its the pressure that would need to be applied to a pure solvent to keep it from osmosing into the solution through a semipermeable membrane.
The obligate halophile halobacterium salinarum maintains a high intracellular concentration of potassium(K) in order to avoid osmotic shock.
