Frage 1 Bericht
The part of the ruminant stomach from which digestive juices secreted is the
Antwortdetails
The part of the ruminant stomach from which digestive juices are secreted is the abomasum. Ruminants, such as cows, sheep, and goats, have a four-compartment stomach that allows them to break down tough plant material through a process of fermentation. The four compartments of the ruminant stomach are the rumen, reticulum, omasum, and abomasum. The rumen and reticulum are the first two compartments and work together to break down food through fermentation and mixing with digestive juices. The omasum is the third compartment and is responsible for absorbing water and some nutrients. The abomasum is the fourth and final compartment and is equivalent to the true stomach in non-ruminant animals. It is where the majority of digestive juices are secreted and where the final stages of protein digestion occur. The abomasum also secretes enzymes that help to break down fats and carbohydrates. In summary, while the rumen and reticulum of the ruminant stomach are responsible for fermentation and mixing of food, it is the abomasum where the majority of digestive juices are secreted and where the final stages of protein digestion occur.

Antwortdetails
The pox disease in livestock are caused by "viruses". Pox diseases are a group of viral infections that affect livestock, including cattle, sheep, and goats. These diseases are highly contagious and can spread rapidly through populations of animals, causing skin lesions, respiratory symptoms, and, in severe cases, death. Bacteria, protozoa, and fungi are not the cause of pox diseases in livestock. Bacteria are single-celled microorganisms that can cause a wide range of diseases in livestock, but they are not responsible for pox diseases. Protozoa are single-celled organisms that can also cause diseases in livestock, but they are not the cause of pox diseases. Fungi are multicellular organisms that can cause infections in livestock, but they are not the cause of pox diseases.
Frage 3 Bericht
The degree of responsiveness of demand to change in the price of goods or produce is referred to as
Antwortdetails
The degree of responsiveness of demand to a change in the price of goods or produce is referred to as price elasticity of demand. Price elasticity of demand is a measure of how much the quantity of a good or product demanded will change in response to a change in its price. If the quantity demanded changes a lot in response to a change in price, the demand is said to be elastic, and the price elasticity of demand will be high. If the quantity demanded changes only a little in response to a change in price, the demand is said to be inelastic, and the price elasticity of demand will be low. For example, if the price of a gallon of milk were to increase by 50%, and the quantity of milk demanded were to decrease by only 10%, the demand for milk would be said to be inelastic. On the other hand, if the price of a luxury car were to increase by 50% and the quantity demanded were to decrease by 50%, the demand for luxury cars would be said to be elastic. Price elasticity of demand is an important concept in economics, as it helps producers and policymakers understand how consumers will respond to changes in price. It can also help businesses make decisions about pricing strategies, such as whether to lower prices to increase demand or raise prices to increase profits.
Frage 4 Bericht
A good silage should be free of
Antwortdetails
A good silage should be free of moulds. Silage is made by fermenting green fodder in a silo or pit to preserve it as animal feed. Moulds can grow on the silage if the conditions are not right, such as when there is too much moisture or oxygen in the silo. This can lead to a decrease in the quality of the silage, as well as potential health problems for the animals consuming it. Mouldy silage can contain mycotoxins, which are toxic substances produced by certain types of moulds. When consumed by animals, mycotoxins can cause a range of health problems, including reduced milk production, poor weight gain, and even death in severe cases. Therefore, it is important to ensure that silage is made under the right conditions, such as with the correct moisture content and sufficient compaction to exclude oxygen. This will help to prevent the growth of moulds and ensure that the silage is of good quality for animal consumption.
Frage 5 Bericht
Reduction of ten seedlings of maize to two per stand is referred to as
Antwortdetails
The reduction of ten seedlings of maize to two per stand is referred to as Thinning. Thinning is the process of removing some of the weaker or excess seedlings in a plant stand to allow the remaining plants to have enough space, light, and nutrients to grow properly. This helps to ensure that each plant has enough resources to reach maturity and produce a good yield. In the case of maize seedlings, if there are too many plants growing in close proximity, they may compete with each other for resources, leading to smaller and weaker plants. By thinning the stand down to two seedlings per stand, you are providing the remaining plants with the necessary resources they need to grow strong and healthy.
Frage 6 Bericht
Maize grows best on
Antwortdetails
Maize grows best on loamy soil. Loamy soil is a mixture of sand, silt, and clay, and is considered one of the best soil types for growing crops like maize. This is because loamy soil has a balanced mix of particles that allows it to hold water and nutrients well while also providing good drainage. The balance of sand, silt, and clay in loamy soil allows for good aeration, which is important for healthy root growth in maize plants. Sandy soil, on the other hand, has larger particles that do not hold water or nutrients well and can lead to poor crop growth. Sandy-clay soil and silty-clay soil have higher clay content, which can lead to poor drainage and waterlogging in wet conditions, making them less suitable for growing maize. In summary, maize grows best on loamy soil, which has a balanced mix of sand, silt, and clay that provides good drainage, aeration, and nutrient holding capacity for healthy crop growth.

Frage 8 Bericht
The process whereby rocks are broken down into small particles through both physical and chemical factors is known as
Antwortdetails
The process whereby rocks are broken down into small particles through both physical and chemical factors is known as weathering. Weathering is the process by which rocks and minerals are broken down into smaller particles, called sediment, through a combination of physical and chemical processes. Physical weathering can occur when rocks are exposed to factors such as temperature changes, freeze-thaw cycles, or abrasion by wind or water. Chemical weathering can occur when rocks are exposed to substances like acid rain or the natural acids produced by organic matter in soil. Over time, these processes can cause rocks to break down into smaller and smaller particles, eventually forming soil and sediment that can be transported by erosion.
Frage 9 Bericht
Which one of these is not a factor that affect change in supply of agricultural produce?
Antwortdetails
Fixed cost is the option that does not affect the change in supply of agricultural produce. Fixed costs are the expenses that do not change with changes in the level of output or production, such as rent or salaries. In contrast, factors that affect the change in supply of agricultural produce are those that influence the quantity of goods that farmers are willing and able to produce and sell in a given period of time. Technology can increase the efficiency and productivity of agricultural production, leading to an increase in supply. Changes in the cost of production, such as changes in the price of inputs like fertilizer or labor, can affect the profitability of farming and impact the supply of agricultural produce. Changes in commodity prices can also affect the supply of agricultural produce, as farmers may be more willing to produce more goods if they can sell them at higher prices. In summary, while fixed costs are an important consideration in farming and agricultural production, they do not directly affect the change in supply of agricultural produce.

Crop rotation involves the growing of crops one after other in a particular sequence
Frage 14 Bericht
Which of the following cereal crops most requires nursery practices?
Antwortdetails
Rice is the cereal crop that most requires nursery practices. Rice is typically started from seed in a controlled nursery environment before being transplanted to the field. This process is known as "direct seeding" and it involves sowing the rice seeds in a seedbed or nursery, where they can be carefully tended and protected from pests and other threats until they are strong enough to be transplanted. Nursery practices for rice can include things like preparing the seedbed, selecting high-quality seeds, managing water and nutrients, controlling pests and diseases, and ensuring proper spacing between seedlings. Once the seedlings have grown to a certain size and are strong enough to withstand transplanting, they are carefully uprooted and moved to the main field. While other cereal crops like maize, millet, and guinea corn can also benefit from certain nursery practices, they are typically started directly in the field through methods like broadcasting or drilling. Rice, on the other hand, is more commonly transplanted from a nursery, making it the cereal crop that most requires nursery practices.

Maize rust can have a significant impact on crop yield and quality, and it is important for farmers to take steps to prevent and control the disease. This can include the use of disease-resistant maize varieties, crop rotation, proper sanitation practices, and timely application of fungicides when necessary. So, the correct answer is fungus.
Frage 17 Bericht
In animal nutrition, iodine is essential for the production of
Antwortdetails
Iodine is essential for the production of thyrozine, which is a hormone produced by the thyroid gland. The thyroid gland is a small butterfly-shaped gland located in the neck. Thyrozine helps regulate the metabolism of animals and other organisms, which is the process by which they use energy from food to carry out their daily activities. Iodine is important because it is a key component of thyrozine. Without enough iodine, the thyroid gland cannot produce enough thyrozine, which can lead to a variety of health problems, including a slow metabolism and weight gain. In conclusion, iodine is an essential nutrient for animals, and it is important for the production of the hormone thyrozine, which helps regulate metabolism.
Frage 18 Bericht
The demand for agricultural produce is generally
Antwortdetails
Demand for most farm products is inelastic. People can consume only so much then they are satiated. Even if price drops they will not buy much more. When demand is inelastic a drop in price that spurs more quantity being sold results in lower revenue and profit for the producer.
Choice B is correct. A price inelastic demand would mean that an increase in price would not necessarily lead to a decline in quantity demanded or in case it does proportion of quantity change would be lesser vis a vis the change in price.
Demand tends to be price inelastic for agricultural produce for the following reasons.
1. Price changes don't affect consumption much
2. These produce are mostly necessities
3. Possibility of postponement is not there for most of these produce

Frage 23 Bericht
Which one of these is not part of a disc plough?
Antwortdetails
Planter is not part of a disc plough. A disc plough is a farm implement that is used for primary tillage to break up and loosen soil in preparation for planting. It typically consists of a series of individual discs, which are arranged in a line and mounted on a frame. The coulter is a vertical blade that cuts through the soil and creates a furrow for the discs to follow. The discs themselves are typically concave and have a sharp edge, which slices through the soil and turns it over. The furrow wheel follows behind the discs and helps to control the depth of the ploughing. The disc scraper is a blade or bar that is attached to the frame of the plough and helps to prevent the discs from becoming clogged with soil or debris. It is typically positioned behind the discs and scrapes away any material that may be caught between them. Therefore, the planter is the option that is not part of a disc plough. A planter is a separate implement that is used for planting seeds or seedlings into the soil, and is not typically integrated into the design of a disc plough.

The other three options, funnel, isthmus, and ovary, are all parts of the hen's reproductive system. The funnel is a funnel-shaped opening in the female reproductive system that connects the oviduct and the cloaca, the isthmus is a narrow part of the oviduct that connects the funnel to the uterus, and the ovary is a reproductive gland that produces the eggs.
Frage 25 Bericht
Which of the following is not a sign of heat in animals?
Antwortdetails
Mucous discharge from the rectum is not a sign of heat in animals. Heat, also known as estrus, refers to the period in the reproductive cycle of female animals when they are fertile and can mate with males to produce offspring. During heat, females exhibit various physical and behavioral changes to signal their readiness to mate. These changes include swelling of the vulva, increased vaginal discharge, mounting behavior, and restlessness. Mucous discharge from the rectum is not a typical sign of heat in animals. It can indicate a digestive issue or infection, and it is not related to reproductive readiness. Therefore, if you observe mucous discharge from the rectum in your animal, it is important to seek veterinary attention to identify the cause of this symptom.
Frage 26 Bericht
In order to eliminate food shortage, farm as should
Antwortdetails
To eliminate food shortage, farmers should cultivate more varieties of crops. This means growing different types of crops that are suitable for the local climate and soil conditions. By growing a variety of crops, farmers can reduce their dependence on a single crop, which can be vulnerable to pests, diseases, and other environmental factors. Furthermore, farmers can also use crop rotation, a farming technique where different crops are planted in a specific sequence, to improve soil fertility and reduce pests and diseases. This helps to increase crop yields and ensure a more sustainable food supply. While land tenure by inheritance and constructing farm buildings can be helpful for farmers, they may not directly address food shortage. Similarly, shifting from crop to animal production may not be the most effective solution, as it can require more resources and land to produce the same amount of food.
Frage 27 Bericht

Antwortdetails
The parent material of a soil is formed from the disintegration of rock. Soil is made up of many different components, including organic matter, minerals, water, and air. However, the most important component of soil is the parent material, which is the rock or mineral that the soil is derived from. Over time, rock is broken down into smaller and smaller pieces by physical and chemical weathering processes. This process can take thousands of years, but eventually, the rock is reduced to small particles like sand, silt, and gravel. These smaller particles become the building blocks of soil, and they provide the structure and nutrients that plants and other organisms need to grow. In conclusion, the parent material of a soil is formed from the disintegration of rock, which is broken down over time into smaller particles like sand, silt, and gravel. These particles become the foundation of soil and provide the structure and nutrients that plants and other organisms need to grow.

However, on average, it takes about 4 to 5 months for groundnuts to reach maturity and be ready for harvesting.
Frage 38 Bericht
Which of the following nutrient element is not a micro-nutrient
Antwortdetails
Calcium is not a micro-nutrient. Nutrients required by plants for growth and development can be classified into two categories: macro-nutrients and micro-nutrients. Macro-nutrients are nutrients that are required in larger amounts by plants, while micro-nutrients are required in smaller amounts. Calcium is a macro-nutrient that is essential for plant growth and development. It is required in relatively large amounts and plays an important role in cell wall formation, root development, and the regulation of other nutrients in the plant. In contrast, Iron, Manganese, and Boron are micro-nutrients that are required by plants in smaller amounts. These micro-nutrients are important for various functions in the plant, such as photosynthesis, enzyme activation, and hormone regulation. Therefore, Calcium is not a micro-nutrient because it is required in larger amounts by plants compared to micro-nutrients like Iron, Manganese, and Boron.
Frage 39 Bericht
Which of the following required daily checking in a tractor?
Antwortdetails
The engine oil in a tractor is something that requires daily checking. Engine oil is a vital component of any engine, including those found in tractors. It helps lubricate the moving parts of the engine, reducing friction and heat buildup that can damage the engine over time. It also helps remove contaminants and debris from the engine, keeping it clean and operating smoothly. Because tractors are often used in dusty, dirty, and challenging environments, the engine oil can become contaminated quickly. Therefore, it is important to check the oil level and quality on a daily basis to ensure that the engine is properly lubricated and functioning at optimal levels. While other components like the spark plug, air cleaner, and battery are also important and should be checked regularly, they do not require daily checking like the engine oil. In summary, the component that requires daily checking in a tractor is the engine oil.
Frage 40 Bericht
Oil palm trees do well in soils with pH level of
Antwortdetails
Oil palm trees do well in soils with a pH level between 5.5 and 6.5. Soil pH is a measure of the acidity or alkalinity of the soil, and it affects the availability of nutrients to plants. The pH scale ranges from 0 to 14, with a pH of 7 considered neutral. Values below 7 are considered acidic, and those above 7 are alkaline. Oil palm trees have specific nutrient requirements, and the availability of these nutrients can be affected by soil pH. Soils with a pH level between 5.5 and 6.5 are considered slightly acidic to neutral, which is optimal for oil palm growth and production. In soils that are too acidic or alkaline, certain nutrients may be unavailable to the plant, leading to nutrient deficiencies and reduced yields. It's worth noting that different soils have varying levels of acidity or alkalinity, and it's important to test the soil pH level before planting oil palm trees to ensure the soil is suitable for the crop. Soil pH can be adjusted through the application of soil amendments such as lime to increase the pH or sulfur to decrease the pH, depending on the specific needs of the soil and the crop.
