Answer:
Polycythemia Vera
Explanation:
Polycythemia Vera can be described or known to be a type of blood cancer. And its effect is that, it makes the bone marrow to make or produce too many red blood cells, which can thicken the blood, slowing its flow, and can cause serious problems, such as blood clots, strokes, weakness among others.
Some of the symptoms of Polycythemia vera are
* Headaches, dizziness, and weakness.

* Double or blurred vision and blind spots.
In conclusion, it should be understood that there is no cure for polycythemia vera. And treatment only focuses on reducing the risk of complications.
Answer:
Covalent bonds are the types of Bond which is formed by sharing of an electron between two atoms of same element or two different elements. The bond which is formed by the completely lost or gained of an atom is known as ionic bond.
Explanation:
The most common example of covalent bond is formed from carbon atom. The valence of carbon atom is 4. Therefore, it is very hard to gain or lose an electron from the carbon atom. Therefore, the carbon tends to share the electron instead of completely losing or gaining the electron.
Ionic bond is very common and it can be formed by many elements from the periodic table. Ionic bond is more stable and stronger when compared to the covalent bond in nature.
Answer:
(1) It is known as a prosthetic group as heme consist of a protoporphyrin ring and a central iron atom. A prosthetic group is a specific non-polypeptide unit which is required for some protein's biological function.
(2) Coenzyme.
(3) It is known as an example of a cofactor as it is not a permanent part of the enzyme.
(4) It is known as a prosthetic group as it is permanently attached to the enzyme.
(5) Coenzyme-A.
(6) Cofactor.
(7) Cofactor.
When blood is in the lungs,
where oxygen is plentiful, oxygen easily binds to the first subunit and then quickly fills up the remaining ones. Then, as blood circulates through the body, the oxygen level drops while that of carbon dioxide increases. In this environment, hemoglobin releases its bound oxygen.
