Because there is no salt there.
When sodium and chlorine atoms come together to form sodium chloride (NaCl), they transfer an electron. The sodium (Na) atom transfers one electron to the chlorine (Cl) atom, so that they both have full outer shells. ... The chloride ion now has eighteen electrons and seventeen protons, so it's become a negative ion.
Both a nasogastric tube and a chest tube are inserted.
The flower structures are identified above:
The functions are as follows.
Petal- large and brightly coloured to attract insects.
Sepal- protects the flower whilst in bud.
Stalk- supports the flower to make it easily seen by insects, and to be able to withstand the wind.
Stamen- male reproductive organ of the flower, made up of the anther and filament.
Anther- contains pollen sacs, in which pollen grains are formed. Pollen contains the male sex cells.
Filament- supports the anther.
Carpel- female reproductive organ if the flower. Made up of the stigma, style and ovary.
Stigma- sticky surface to the ovary, through which pollen tubes grow.
Style- links the stigma to the ovary through which pollen tubes grow.
Ovary- contains ovules which form into seeds when fertilised.
