The coronary arteries provide the main blood supply to the heart. The coronary arteries also supply the myocardium with oxygen to allow for the contraction of the heart and thus causing circulation of the blood throughout the body.

- NHRC is an independent commission set up by the law in 1993.
- Like the Judiciary, the commission is independent of the government.
- The commission is appointed by the President and includes retired judges, officers and eminent citizens.
- It does not bear the burden of deciding cases. So it can focus on helping the victims secure their human rights.
- These include all the rights granted to the citizens by the constitution.
- The NHRC cannot punish the guilty. That is the responsibility of the courts.
- Like any court, it can summon witnesses, question any government official, demand any official paper, visit any prison for inspection or send its own team for on-the-spot inquiry.

Due to its smaller size and unavailability of d-electrons boron is found to exhibit properties which are in contrast to the other elements of the boron family. These properties are known as anomalous properties of boron. Some of these anomalous properties are discussed below.
- Except for boron, the compounds of the elements of the boron family like tetrahedral [M(OH)4]– and octahedral [M(H2O)6]3+ (where M denotes the member of boron family) exists in an aqueous medium.
- The maximum covalence of boron is 4 due to the absence of d orbitals.
- Boron is a metalloid while the rest of the family are post transition metals.
- The boron oxides and hydroxides are acidic in nature, whereas the other elements in the family form oxides and hydroxides which are amphoteric in nature.

Borax acid is formed when it is acidified.
Na2B4O7 + 2HCl + 5H2O → 2NaCl + 4H3BO3
Borax is a weak acid so it is slightly hydrolyzed in solution and is alkaline in nature.
B2O72- + 7H2O →2OH- + 4H3BO3

When heated, borax undergoes various transitions. It first loses water molecules and swells. Then, it turns into a transparent liquid, solidifying to form a glass-like material called borax bead.

Rubisco stands for Ribulose bisphosphate carboxylase. Rubisco is a carboxylase/oxygenase enzyme which plays a dual role in Calvin cycle. This is because the active site of enzyme is same for both carboxylation and oxygenation reactions.
*Ribulose bisphosphate carboxylase is an enzyme which catalyses the combination of RuBP with carbo dioxide to give rise to two molecules of phosphoglyceric acid (PGA) during Calvin cycle.
*When there is less concentration of Carbon dioxide and high Oxygen concentration, RuBP is oxidised to one molecule of phosphoglycolate and one molecule of PGA during Calvin cycle.
