The Answer is A.) Carbon dioxide
Cause it is produced as a waste product during respiration in the cells of the body tissues, diffuses into the blood.
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.
As the exercise progresses, muscular activity increases venous return. This increases the pre-load on the right ventricle. During venous exercise, the rhythmic pump of the muscles facilitates venous return by forcing the blood through one way valves that lead to the heart. Additionally, increased lung activity which creates a change in thoracic pressure that draws blood towards the heart. Regular exercises improves the venous return by increasing total blood volume, increasing end diastolic volume and increasing the size and contractile strength of the heart muscle.
Molecules are formed by same types of atom whereas compounds are formed by different atom with various types of bonding..
Answer:
Binary fission.
Explanation:
Reproduction may be defined as the process of production of the offspring to produce more of its own kind. Two main types of reproduction are sexual reproduction and asexual reproduction.
Asexual reproduction involves only one one parents and produce the offspring that has same genetic material. Binary fission is the main type of the cell division used by unicellular organism. The cell divide into two daughter cells with the same genetic constituents.
Thus, the answer is binary fission.
