The sodium-potassium pump of cell function is to take 2 potassium atoms into cells and dump the 3 sodium outside cells. The pump is also needed ATP as energy to make it work. That is why the pump sometimes referred as Na3/K2 ATPase pump.
The pump cannot do these things separately. That means if there are much potassium outside cells but there is no sodium, the pump will catch and keep the potassium then wait until they find sodium inside cells. If there is no sodium inside cells, the pump will not work even if there is much potassium outside.
Carbon monoxide : mixture, cigarette smoke : element and ice : element ,none of them are correctly matched, therefore option 3 is correct'
Crystalline structures are created when water molecules have been organized in an ordered, cage-like form. Crystalline compounds, such as ice particles as well as water molecules, are composed of particles or molecules which are arranged in a particular order to produce an ordered component known as just a crystalline compound.
Even though it is made up of a chemical link between an atom of carbon and an atom of oxygen, carbon monoxide would be a pure material. There is only one kind of molecule that makes up carbon monoxide, when nothing is physically mixed with that as well.
carbon monoxide = pure substance
cigarette smoke = mixture
Ice = element
Hence, carbon monoxide : mixture, cigarette smoke : element and ice : element ,none of them are correctly matched, therefore option 3 is correct'

Answer:
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
Explanation:
Matter is defined as a physical substance that occupies space and has mass.
Therefore, jelly and sponge are examples of matter.
Answer:
ethanol
Explanation:
CO2 is carbon dioxide
C2H5OH is ethanol and we know that because that is what is left after taking out the CO2
