Inhales. Oxygen - good for the body - gives it to the Circulatory System to be transported throughout the body through the blood. Digestive System gets nutrients from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go.

I might be a little late to answer your question. I'm sorry!
Answer:
Potassium compounds are quite common and are extremely useful for a variety of purposes. Potash and other potassium compounds have been used for centuries in the manufacture of glass products. Today 95% of the potassium compounds gathered in the world is used in the manufacture of fertilizers.
Potassium dichromate is an inorganic chemical compound possess immense industrial and laboratory importance. It is an orange crystalline solid with the chemical formula K2Cr2O7. It is a strong oxidizing agent and is soluble in water. It is used in the volumetric estimation of ferrous salts, iodides and sulphides for the preparation of chrome alum, chrome yellow and chrome red.
Each mole of bromine atoms must accept one mole of electrons to form one mole of bromide ions (Br-). Bromine gas is diatomic, which means that each mole of bromine gas contains two moles of bromine atoms. Therefore, in order to reduce one mole of bromine gas to form bromide ions, two moles of electrons must be added.
The energy required or released in this process is known as the electron affinity.
Na -k pumps couple atp hydrolysis with the transport of Na and k.
Both ions are used for active transport.
d. K+ and Na+ both diffuse into the cell along their concentration gradients and drive the transport of glucose.
Na/K pump is a pump located on the plasma membrane which uses ATP to move 3 Na ions out the cell and brings in 2 K ions into the cell. It is an example of primary active transport. As a consequence, concentration of Na is higher outside the cell, while K concentration is higher inside the cell.
Glucose is transported in the cell against its gradient, together with Na ions (symport) which move down their concentration gradient.
This is an example of secondary active transport because it uses the energy from the primary active transport to move other substances such as glucose against their own gradients.
