Farmers prefer apomictic seeds over hybrid seeds for the following reasons:
- Genetic Uniformity: Apomictic seeds are genetically identical to the parent plant, ensuring uniform traits in the crop, such as yield and quality.
- Cost-effectiveness: Farmers can reuse apomictic seeds without purchasing new seeds every season, reducing overall costs.
Differentiate between spermatogenesis and oogenesis in humans on the basis of the following:
(a) When the process is initiated.

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
