Diffusion and Osmosis
Most common oxidation state of Gold is 0, because its most common form is its elementary form.
Ionizing radiation is the most common form of mutagen.
NAD+ is the oxidized form of the most common electron carrier needed in both glycolysis and the Krebs Cycle.
Iron
The most common form is the pentahydrate.
It is a type of passive diffusion, as the water travels along a concentration gradiant. As opposed to active transport, where the substances can pass against a concentration gradiant.
Rail transportation is the most common form of LONG DISTANCE transport in China.
The most basic difference between active and passive transport is that active requires energy while passive does not. You would require active transport if the substance is going against the concentration of molecules inside and outside of the membrane or if the substance is particularly large. Passive is more for smaller molecules that go with the concentration of the molecules inside and outside of the membrane.
it depends most of the time YES
the most popular transport for the tourists is air transport
Osmosis is the diffusion of water trough a selectively permeable membrane. However, water passes quite easily across most membranes. So it's mostly known as passive transport

There are multiple ways for cells to transport things across a difference in concentration. The most common process is diffusion, which is the movement from high concentration to low. Osmosis is the most popular example of this. Facilitated Diffusion is basically diffusion with the use of proteins that are specified for certain molecules. Active Transport is the method by which molecules are transported from low concentration to high concentration.

Trams are the most visible public transport within the Melbourne CBD. Trains form the second most visible public transport system leading out to the suburbs. Cars and other road transport like busses also form a part of the transport network in Melbourne.
