The germial epithelial cells divide repeatedly until many diploid oogonai are formed. The oogonia grow to form primary oocytes. Each primary follicle. The gets surrounded by a layer of granulosa cells and then called the primary follicle. The primary follicle get surrounded by more layers of granulosa cells and called secondary follicales.
The secondary follicle soon trasforms into a tertiary follicle which is characterised by a meiotic division to become a secondary oocyte and a fisrt polar body (hapliod).
The tertiary follicle furthre changes into the mature follicle or Graaflan folllcle. follicle. The Graafian follicle now ruptures to release to release the secondary oocyte (ovum) from the ovary by the process called ovulation.

Michael joins private limited company Dealing in electronics as a human resource manager. Through a series of interactions with his team during lunch breaks, he comes to know that quite a few managers at middle and senior levels have recently left the organisation as their promotions were overdue. Therefore, in order to reinstate the confidence of the staff he lays out a dear cut plan consisting of a set of general guidelines for both time bound and performance related appraisals of the managers at all levels. Moreover, he develops standardised processes containing a series of steps specified in the chronological order for its implementation. Distinguish between the two types of plans as identified in part 1

Read the following text and answer the following questions on the basis of the same: At power plant, a transformer increases the voltage of generated power by thousands of volts so that it can be sent of long distances through high-voltage transmission power lines. Transmission lines are bundles of wires that carry electric power from power plants to distant substations. At substations, transformers lower the voltage of incoming power to make it acceptable for high volume delivery to nearby end-users. Electricity is sent at extremely high voltage because it limits so-called line losses. Very good conductors of electricity also offer some resistance and this resistance becomes considerable over long distances causing considerable loss. At generating station, normally voltage is stepped up to around thousands of volts. Power losses increase with the square of current. Therefore, keeping voltage high current becomes low and the loss is minimized. Another option of minimizing loss is the use of wires of super-conducting material. Super-conducting materials are capable of conducting without resistance, they must be kept extremely cold, nearly absolute zero, and this requirement makes standard super-conducting materials impractical to use. However, recent advances in super-conducting materials have decreased cooling requirement. In Germany recently 1 km super-conducting cable have been installed connecting the generating station and the destination. It has eliminated the line loss and the cable is capable of sending five times more electricity than conventional cable. Using super-conducting cables Germany has also get rid of the need of costly transformers. Transformers generate waste heat when they are in operation and oil is the coolant of choice. It transfers the heat through convection to the transformer housing, which has cooling fins or radiators similar to heat exchangers on the outside. Flush point is a very important parameter of transformer oil. Flashpoint of an oil is the temperature at which the oil ignites spontaneously. This must be as high as possible (not less than 160^(@)C from the point of safety). Fire point is the temperature at which the oil flashes and continuously burns. This must be very high for the chosen oil (not less than 200^(@)C ). Flush point of an oil is

The implantation process involves the following steps : (I) The morula continues to divide and transforms into blastocyst as it moves further into the uterus. (II) The uterine cells divide rapidly and the blastocyst gets covered by them. (III) Morula is formed. (IV)As the zygote moves through the isthmus of the oviduct towards the uterus, it undergoes mitotic division and forms 2, 4, 8, 16 daughter cells called blastomeres. Choose the correct sequence:
