BACTERIA   :   

Microscopic organisms whose single cells have neither a membrane-bounded nucleus nor other membrane-bounded organelles like mitochondria and chloroplasts.

BACTERIOLOGY   :   

The branch of science under microbiology that studies unicellular, microscopic organisms known as bacteria.

BANDWIDTH   :   

It is the measurement calculated in bits per second, to know the amount of data that can be sent through a connection.

BAR   :   

A unit of pressure, equal to the sea-level pressure of Earth's atmosphere; 1 bar = 0.987 atmosphere = 101,300 pascals = 14.5 lbs/square inch = 100,000 Newtons per square meter.

BAROMETER   :   

A device used to measure the pressure of the atmosphere. The barometer unit of measure is called millibars.

BASALT   :   

A general term for dark-colored, igneous rocks composed of minerals that are relatively rich in iron and magnesium.

BASE   :   

A bitter tasting substance (and often slimy) - the opposite of a acid substance. Base solutions will turn a litmus blue.

BASE LOAD POWER   :   

The average amount of electricity consumed at any given time. Base load power stations are designed to operate continuously, unlike peaking power stations that generally run only when there is a high demand.

BATTERY   :   

A device that produces electricity by means of chemical reaction. A battery consist of one or more units called electric cells. Each cell has all the chemicals and parts needed to produce an electric current.

BERNOULLI EFFECT   :   

Also known as Venturi effect, means that decrease in the pressure of fluid increases the velocity of the fluid. The Bernoulli's principle and the equation of continuity form the basis of Bernoulli's effect.

BREMSSTRAHLUNG   :   

When a fast charged particle like an electron slows down as it passes to matter. Thus, loses energy in the form of electromagnetic radiation. This is known as Bremsstrahlung. This is a German word that means 'breaking radiation'.

BUCCAL CAVITY   :   

The first part of the alimentary also known as the mouth is called the buccal cavity. This portion receives the food and begins digesting the food by mixing saliva with food.

BUFFER   :   

An aqueous solution of weak acid and its conjugate acid or weak base and its conjugate acid is known as buffer solution. The buffer solution is used to maintain the pH value constant in many chemical applications.

BUTTE   :   

A conspicuous, isolated, flattop hill with steep slopes.
