Given the following equation, 2 N2 + 5 O2 â 2 N2O5, 1.25 moles of nitrogen requires _____ moles of oxygen.
Causes of sickle cell anaemia. Sickle cell anaemia is caused by a genetic mutation that affects the normal development of haemoglobin. A genetic mutation is a permanent change in the normal pattern of genetic information inside all living cells.This results in one or more of the body's processes not working properly.ickle cell anaemia is caused by a genetic mutation that affects the normal development of haemoglobin.

Sickle cell anemia is a genetic disease with severe symptoms, including pain and anemia. The disease is caused by a mutated version of the gene that helps make hemoglobin  a protein that carries oxygen in red blood cells.People with two copies of the sickle cell gene have the disease.NA and Mutations : A case study of the effects of mutation: Sickle cell anemia. The mutations that cause sickle cell anemia have been extensively studied and demonstrate how the effects of mutations can be traced from the DNA level up to the level of the whole organism.
