In this type, the females carry two different types of sex chromosomes (ZW) and are heterogametic while males carry identical sex chromosomes (ZZ) and are homogametic. The ova will be of two types: Zcarrying and Wcarrying while all sperms will be only Z-carrying. The o..

P-type Semiconductor - When the impurity atom is a trivalent atom say indium, boron or aluminium, these atoms will replace the silicon atom as shown. The 3 valence electrons of Indium atom bond covalently with 3 of silicon atom. There is one incomplete covalent bond due to deficiency of a..

Angle - When two straight lines meet at a common point, they form an angle. and are called arms of the angle BAC. The point 'A' is called the vertex. The angle formed by the two rays AB and AC is denoted by the symbol BAC. If there is only one angle at A, then the angle BAC may be denoted ..

It is seen that energies of free electrons in n type are slightly less than that of free electron in lowest energy level in conduction band. The energy 0.05 eV is comparable to the thermal energy of electron and so a very small energy is supplied to excite electrons from donor levels..

Fibrocytes are stellate or star shaped cells, which produce the matrix and white and yellow fibres. Macrophages are irregular, amoeboid cells which can ingest bacteria and other disease producing germs by phagocytosis. Mast cells are spherical or oval cells, which produce the anticoagulant ..
