Electrical protection (Cathodic protection)
The iron object is connected to a more active metal either directly or through a wire. Fe acts as the cathode. The more reactive metal is the anode. It loses electrons and gradually disappears. Example: Fe can be connected to Mg, Zn or Al which are called the sacrificial anodes. Used for..

The Forest Conservation Act 1980 was passed to check the indiscriminate use of forest for other purposes. This act was amended in 1988 which made provisions for dealing with violators. Indian Wildlife Protection Act 1972 was re-amended in 1983, 86 and 1991. I..
Associated structures
There are certain structures associated with the eyes and carry out, mainly, the function of protection. These structures ar..
Analogous Structures
There appear to be many structures that are similar because of the function they carry out and in their external appearance. However, these structures differ internally. Such structures are called analogous structures. For example, wings of bat and butterfly..

Each stomata consists of a minute pore called stoma surrounded by two guard cells. The stoma acts as a turgor operated valve which closes and opens according to the turgidity of guard cells. The guard cells are the only epidermal cells that contain chloroplasts. The guard cells have unev..
Structure of the Heart
External view of a Mammalian Heart The heart is a 4 chambered muscular pump located inside the chest or the thoracic cavity. It is a mesodermal derivative and is a myogenic heart. The heart is surrounded externally by a thin, transparent 2 layered serous sac called pericardium. The narrow cavi..

Research organizations have developed improved storage structures which have proved comparatively safe for the storage of grains. In these structures, temperature, moisture, oxygen and carbon-di-oxide can be adjusted to protect the grains. The structures are..
Structural Genes (Cistrons)
These genes produce mRNAs (transcription), which in turn synthesize specific polypeptides on the ribosomes (translation). The polypeptides so formed act as enzymes to catalyse some metabolic reaction in the cell. An operon may have one or more structural genes. The lactose or l..
Structures of Starch and Cellulose
Amylose is water soluble, long unbranched (linear) chain with 200-1000 D-glucose units. These units are joined together by a (1 4) glycosidic linkage involving C-1 of one glucose unit and C-4 of the other glucose unit. Its molecular weight can range from 10,000 to 500,000. Amylose gives blue color ..
Vitamin E
This vitamin is named as tocopherol. Nearly about 8 tocopherols are identified - a , b , g etc. Among these -tocopherol is most active. Vitamin E is stored in adipose tissue, liver and muscle. It acts as a scavenger and is essential for membrane structure, cellular respirat..
