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.
Adaptive immunity is developed after an organism is exposed to a disease. Lymphocytes, who years later respond to repeated exposure to the infection are called;
Lymphocytes are basically classified into two namely, the B and T cells. The B cells give antibody-mediated immunity while the T cells provide cell-mediated immunity.
The memory cytotoxic T lymphocyte is stored as reserve in the body so that in the event of the reoccurrence of a disease, it will resolve itself into the cytotoxic T cell that will fight the disease antigen.

Answer:
10 units
Explanation:
Each organism that the energy has to got through leaves only 10% of the energy that they got. So for each organism that consumes the energy, there is only 10% left for the next organism that consumes it. Tertiary consumers are level 4, so you have to take 10% of 100,000 4 times to get the answer 10 units of energy is left.
