What is the main reason for raising a shed on a seedling bed?

You're on a roll — here are the solutions for questions 13 to 25: Question 13: Excessive amount of nitrogen in the soil leads to A. delayed maturity of crops. Explanation: While nitrogen promotes vegetative growth, too much can delay flowering and fruiting, thus delaying the overall maturity of the crop. Question 14: A substance that contains 10 electrons and 11 protons is D. an ion. Explanation: An atom with 11 protons is Sodium (Na). If it has 10 electrons, it has lost one electron, resulting in a net positive charge (Na^+), which is an ion. Question 15: Which of the following practices reduces the speed of run-off along sloped lands? D. Strip cropping. Explanation: Strip cropping involves planting different crops in alternating strips, often along the contours of a slope. The strips of dense vegetation act as physical barriers, slowing down the flow of water and trapping soil, thereby reducing the speed of run-off and erosion. Question 16: The main reason for raising a shed on a seedling bed is to reduce B. intensity of raindrops on bed. Explanation: A shed provides physical protection from harsh weather elements. Heavy raindrops can cause significant physical damage to delicate seedlings, lead to soil erosion, and compact the soil. While it also reduces solar energy, protection from the physical impact of rain is a primary function of a shed. Question 17: Which of the following devices uses magnets in its operation? D. I, II and III. Explanation: • I. Microphone: Many microphones (e.g., dynamic microphones) use electromagnetic
