A vacuole is a membrane-bound organelle which is present in all plant and fungal cells and some protist‚ animal[1] and bacterial cells.[2] Vacuoles are essentially enclosed compartments which are filled with water containing inorganic and organic molecules including enzymes in solution‚ though in certain cases they may contain solids which have been engulfed. Vacuoles are formed by the fusion of multiple membrane vesicles and are effectively just larger forms of these.[3] The organelle has no basic

Willis Mktg 3302 Professor J. Smith 10 June 2011 Week 3 Essay Assignment 2. In the multiple store theory of memory there are three different storage areas within the brain. Sensory memory is where the five senses are put to use and it has unlimited capacity like iconic and echoic storage and has different storage mechanism. However‚ the duration of sensory memory is very limited. Work bench memory is an area of the brain where information is stored for long-term

8. Store grain using appropriate methods Once grain is sufficiently dry and cleaned it should be put in storage. In all cases‚ the moisture content of grain placed in store must be at or below the safe limit (see Section 4 Box 3).

Flywheel energy storage works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. The energy is converted back by slowing down the flywheel.Flywheel energy storage system is one form of energy storage devices. It is basically a rechargeable battery. It is used to absorb electric energy from a source‚ store it as kinetic energy of rotation‚ and then deliver it to a load at the appropriate time‚ in the form that meets the load needs
