MgCl2 dissolves in water because the individual ions in the solid (Mg2+ and Cl-) coordinate with the partial charges in the water molecules. The magnesium cations coordinate with the partially negatively charged oxygen atoms and the chlorine anions coordinate with the partially positively charged hydrogen atoms.
Answer:
b. Vitamin K deficiency inhibits the blood’s ability to clot.
Explanation:
The main form is vitamin K1 (phylloquinone); followed by vitamin K2 (menaquinone), formed from the bacterial action on the large intestine tract and a third compound, vitamin K3 (menadione), a synthetic fat-soluble molecule. These vitamins can be found in many foods: in green vegetables (lettuce, cauliflower and spinach), in tomatoes, Brazil nuts, cashews, potatoes, contained in soybean oil, egg yolk, milk and to a lesser extent in wheat and oats.
Vitamin K participates in blood clotting, its deficiency can make it difficult to stop bleeding. Also causing damage to the body when in excessive concentration, for example: dyspnea (shortness of breath), and chest pain in adults with high vitamin K1 disorder and hyperbilirubinemia in newborns whose mothers in gestation underwent treatment with based on vitamin K3.
Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs from the lungs between the alveoli and a network and a bunch of tiny blood vessels called capillaries, which is located in the walls of the alveoli.
