X is a human being with the reproductive oval shaped almond sized organ Y which releases mature gamete Z monthly once that goes into tube like structure A where it fuses with another gamete called B to form a new cell C. This cell C divides vigorously to form a ball of cells D which gets embedded in the thick lining of organ E of the reproductive system of X where it grows and develops into a foetus. i] Identify X, as male or female. ii] Name the reproductive part Y and give its two functions. iii] Name the gametes Z and B. Iv] Name the process which leads to the formation of C and Identify C. v] Name the ball of cells D. vi] Identify the organ E.

In a hexaonal system system of cycstals, a frequently encountered arrangement of atoms is described as a hexagonal prism. Here, the top and bottom of the cell are refular hexagons, and three atoms are sandwiched in between them. A space-cilling model of this structure, called hexagonal close-paked is constituted of a sphere on a flat surface surrounded in the same plane by six identical spheres as closely as possible. Three spherres are then placed overt the first layer so that they toych each other and represent the second layer so that they toych each other and present the second layer. Each one of the three spheres touches three spheres of the bottom layer. Finally, the second layer is convered with a third layer identical to the bottom layer in relative position. Assume the radius of every sphere to be r . The voume of this hcp unit cell is

There are two types of fertilizers F_1" and "F_2 consists of 10% nitrogen and 6% phosphoric acid and F_2 consists of 5% nitrogen and 10% phosphoric acid. After testing the soil conditions, a farmer finds that he needs atleast 14 kg of nitrogen and 14 kg of phosphoric acid for his crop. If F_1 costs Rs. 6/kg and F_2 costs Rs. 5 kg. Determine how much of each type fertilizer should be used so theat nutrient requirements are met at a minimum cost. What is the minimum cost? Also show graphically.
