Question 6 Report
If urea fertilizer contains 46% nitrogen, calculate the amount of nitrogen in 25kg bag of fertilizer?
Answer Details
The amount of nitrogen in a 25kg bag of urea fertilizer can be calculated by multiplying the total weight of the bag by the percentage of nitrogen in the fertilizer. Since the urea fertilizer contains 46% nitrogen, we can express this as a decimal: 46% = 0.46. Next, we multiply the total weight of the bag (25kg) by the decimal equivalent of the nitrogen content (0.46): 25kg * 0.46 = 11.5kg So, a 25kg bag of urea fertilizer contains approximately 11.5kg of nitrogen.
Question 7 Report
Which of the following fishing gears can be used for total harvesting of pond?
Answer Details
A dragnet can be used for total harvesting of a pond. A dragnet is a type of fishing gear that consists of a large net that is pulled through the water by a boat or by people on the shore. The net is designed to catch all types of fish in the pond, making it an effective way to harvest a large quantity of fish in a short amount of time. Hook and line and harpoon fishing gears are typically used for catching specific types of fish, rather than for total harvesting of a pond. Basket traps are often used to catch crustaceans and other small aquatic animals, rather than fish. While dragnet fishing can be an effective way to harvest a large quantity of fish, it can also have negative impacts on the ecosystem if it is not managed properly. Overfishing and destruction of habitats can result if dragnet fishing is not regulated and monitored.

Agriculture is the main source of food for most populations around the world and plays a crucial role in ensuring food security. Income generation refers to the use of agriculture as a means to earn money. This can be achieved through the sale of crops, livestock, and other agricultural products. Agriculture provides a source of livelihood for millions of people, particularly in rural areas. Provision of employment refers to the creation of job opportunities in the agricultural sector. This includes jobs in farming, processing, and other related industries. Agriculture can help to reduce unemployment, especially in areas where there are limited job opportunities. The objective of provision of shelter is not typically considered one of the main objectives of agriculture. Although, agriculture can play a role in providing materials for building homes, such as wood and other natural resources, the primary focus of agriculture is on food production, income generation, and employment.
Question 15 Report
The practice of mating closely related animals is called
Answer Details
The practice of mating closely related animals is called inbreeding. Inbreeding is when two animals that are closely related, such as siblings or parent and offspring, are bred together. This increases the likelihood that their offspring will have similar traits and characteristics because they share many of the same genes. While inbreeding can lead to the expression of desirable traits, it can also increase the risk of genetic disorders and other health problems. For this reason, many breeders prefer to use outbreeding, or mating animals that are not closely related, to promote genetic diversity and reduce the risk of health problems in their offspring.
Question 16 Report
The effects of practicing crop rotation include the following except
Answer Details
The option that does not describe the effect of practicing crop rotation is "adding humus to the soil." Crop rotation involves planting different crops in a specific sequence in a certain area over time. The purpose of this is to maintain and improve soil fertility, control soil erosion, and prevent the build-up of pests and diseases. By rotating crops, the soil is given a chance to rest and recover nutrients that were taken away by previous crops, leading to healthier soil and better crop growth. On the other hand, adding humus to the soil involves adding organic matter such as compost, leaves, or manure to the soil. This helps to improve soil structure, water retention, and nutrient availability. While adding humus to the soil can complement the effects of crop rotation, it is not a direct result of practicing crop rotation.
Question 17 Report
Ginning is a method of processing
Answer Details
Ginning is a method of processing cotton. Ginning is the process of separating the cotton fibers from the seeds in cotton crops. The cotton fibers are used to make textiles, while the cotton seeds are used for oil production.

Question 19 Report
The horizon of a soil profile which encourages the greatest level of microbial activity is
Answer Details
The horizon of a soil profile that encourages the greatest level of microbial activity is the A horizon. Soil horizons are defined layers in a soil profile, each with its own distinct physical and chemical properties. The A horizon, also known as the topsoil, is the topmost layer of the soil profile and is typically rich in organic matter, nutrients, and water. This layer is also where the majority of soil microbes, such as bacteria, fungi, and other microorganisms, are found. The B horizon, also known as the subsoil, is below the A horizon and is typically more compact and less porous than the A horizon. It contains relatively low levels of organic matter and is not as conducive to microbial activity as the A horizon. The C horizon is the layer of soil material that is below the B horizon and is composed of partially weathered rock fragments and mineral particles. This layer typically has low levels of organic matter and is not as conducive to microbial activity as the A horizon. The D horizon is not present in all soils and is typically composed of consolidated bedrock. This layer is not conducive to microbial activity as it is typically inhospitable to life due to its lack of water and organic matter. So, the answer to the question is the A horizon.

A piece of land is said to be on lease to a farmer when the land is given to him for a specific period of time on rental basis. This means that the farmer has the right to use the land for agricultural purposes for a certain amount of time, usually several years, in exchange for paying a fee or rent to the owner of the land. At the end of the lease period, the farmer must return the land to the owner. This arrangement allows the farmer to use the land without having to purchase it outright, while also providing the owner with a source of income from the rent paid by the farmer.
Question 25 Report
Layer's ration contains more limestone than grower's ration because limestone
Answer Details
Layer's ration contains more limestone than grower's ration because limestone supplies sufficient minerals to layers for shell formation. Layers are chickens that are specifically raised for egg production, while growers are chickens that are raised for meat production. The composition of the feed for these two types of chickens is different, with layer's ration containing more calcium in the form of limestone. Calcium is an essential mineral for the formation of eggshells, and it is important for layers to have a constant supply of calcium in their diet. The higher level of limestone in layer's ration helps to ensure that the layers have access to the calcium they need for strong and healthy eggshells. On the other hand, growers do not require as much calcium in their diet as layers, so their ration contains less limestone.
Question 27 Report
An increase in supply of agricultural produce can be caused by the following factors except
Answer Details
An increase in supply of agricultural produce can be caused by a variety of factors such as reduced cost of production, favorable weather conditions, and reduced taxation. However, the factor that does not contribute to an increase in supply is consumers buying less products. When consumers buy less products, it creates a surplus of the unsold produce and reduces demand for it. When demand for a product decreases, the market price for the product decreases as well, which can lead to a reduction in the supply of that product. In this case, the decrease in consumer demand would actually lead to a decrease in the supply of agricultural produce, rather than an increase.

Question 31 Report
Rain water is made available to crops through
Answer Details
Rain water is made available to crops through root absorption. This is the process where plant roots take in water from the soil. The plant roots absorb the rain water and use it to grow and support the plant. The water is transported from the roots to the leaves, flowers and fruits through a system of tubes in the plant called the xylem. This water is then used by the plant to carry out important functions such as photosynthesis and transpiration. Transpiration is the process where water is released from the leaves into the atmosphere through tiny pores. This helps to regulate the temperature of the plant and also returns some of the water back to the atmosphere, where it can be reused as rain.
