A homogeneous mixture is also called as solution.

The term "solution" is more frequently used when a homogeneous mixture is a liquid, although it is sometimes used if the homogeneous mixture is a gas.

Sometimes the solid particles in a liquid are very small and can pass through a filter paper. For such particles, the filtration technique cannot be used for separation. Such mixtures are separated by centrifugation.

Electronic Flash differs from the consumable bulb flash in important aspects. Instead of creating light by burning up in an atmosphere containing oxygen, a consumable material (each bulb being used therefore only once), it produces a brilliant incandescent by discharging a current for a brief instant through a rarified gas, usually xenon. The gas glows every time the discharge is made through it but it is not consumed, so that many thousands of flashes are obtainable from a single tube, which helps to offset the much higher cost of the initial apparatus.

A normal reading would be any blood pressure below 120/80 mm Hg and above 90/60 mm Hg in an adult. If you're in the normal range, no medical intervention is needed.
