Filtration and dialysis are analytical techniques which are used to separate the particles present in the solution.
The particles that is having a bigger size will be left at the bottom in the solution and the smaller particles will be at the top.
This is because the smaller particles are light in weight and large weight are heavier. Both of the methods are used as a purification technique for the separation of impurities from the solution based on the particle size.
This is true. Think about when you make pasta. The colander acts as a filter and doesn't let the past a through but allows the extra water to escape because the pasta is too big to fit.
A carbon iota can bond with four other iotas and is just like the four-hole wheel, whereas an oxygen iota, which can bond only to two, is just like the two-hole wheel.
