Red blood cells are disc shaped. It is thought one factor that allows them to have this shape is because they do not have a nucleus. This tends to increase amount of space inside the cell for hemoglobin.
They have a flexible disc shape which helps increase the surface- to- area volume ratio which enables oxygen and carbon dioxide to diffuse across the red blood cell's plasma membrane more readily.
Their disc shape also enables them to squeeze through tiny capillaries that are half their size .
The answer is 4Fe+3O2→2Fe2O3

Captive breeding or breeding in the captivity is the conservation technique employed by the government to conserve nature.
Captivity breeding is also known as the captive propagation of animals in which animals are kept either in their natural habitat (ex-situ conservation) or in artificial conditions like in zoos where condition similar to the habitat of animal are created.
The breeding programme aims at conserving the natural habitat of the animals to prevent the endangered species from extinction. The endangered species are at risk of extinction due to loss of fragmentation, pollution, predation and others.
