Concave type of glasses are used in the headlights of the vehicles as the light from the bulb which is at focus will converges out and spreads and reflects back parallely.

Prokaryotic and Eukaryotic cells do share a feature of DNA.

Both prokaryotic and eukaryotic cells have structures in common.

All cells have a plasma membrane, ribosomes, cytoplasm, and DNA.

Prokaryotic cells are primitive cells which have no true nucleus and membrane bound organelles, while Eukaryotic cells are cells that have true nucleus, membrane bound organelles and well defined structures and layouts.

Robert Brown, Scottish botanist, Discovered The Nucleus of a Cell in 1831, London. When Brown was studying orchids under microscope when he observed an opaque area, which he called the "Areola" or "Nucleus", in the cells of the flower's outer layer.

The nucleus was also described by Franz Bauer in 1804 but in detail Robert Brown made it in 1831.

Protoplasm is the living content of a cell that is surrounded by a plasma membrane.

J. E. Purkinje in the year 1839 coined the term 'protoplasm' for the fluid substance of the cell.

As parabola is a locus of a point, which moves so that its distance from focus and directrix is always equal.

The latus rectum of a conic section is the chord (line segment) that passes through the focus, is perpendicular to the major axis and has both endpoints on the curve. The length of the latus rectum is determined differently for each conic.

The length of a parabola's latus rectum is 4p, where p is the distance from the focus to the vertex.

Electrical burns occur principally because of the heat generated by the flow of electrical current through the body.

Burns caused by electricity are divided into three types:

electrical burns,

arc burns, and

thermal contact burns.

Electrical burns can result when a person touches electrical wiring or equipment that is used or maintained improperly.

The Supreme Court of India was established in the year 1950.

Electrical Pressure is also called as Voltage. Voltage is measured in Volts.

Volt : A unit of electrical pressure or Voltage is called Volt.

One volt is the amount of pressure required to cause one ampere of current to flow against one ohm of resistance.

Voltage is also referred to as Electromotive Force or Electrical Potential or Electrical Pressure.
