Detalles de la respuesta
Monoculture is a term associated with plantation agriculture. It refers to the practice of growing only one type of crop or plant species over a large area of land, usually for commercial purposes. Monoculture allows for the efficient and intensive use of resources such as labor, fertilizers, and pesticides. However, it also has several negative impacts on the environment, including soil depletion, increased vulnerability to pests and diseases, and loss of biodiversity.

Some plant diseases are checked during the fallow periods in the bush fallowing system of agriculture because the
Detalles de la respuesta
In the bush fallowing system of agriculture, farmers rotate the use of land between cultivation and fallow periods. During the fallow period, the land is left uncultivated and allowed to rest for some time. This fallow period allows the land to regenerate, and as a result, some plant diseases are checked. The humus accumulates during the fallow period, which increases soil fertility, and can suppress some soil-borne pathogens. Additionally, the disease organisms lose their hosts during the fallow period, and some pathogens die off. Therefore, the answer is "disease organisms lose their hosts and die."

The basin system of irrigation in the Nile Basin is not reliable because
Detalles de la respuesta
The basin system of irrigation in the Nile Basin is not reliable because it depends on the flow of the Nile in a particular year. The amount of water flowing in the Nile River can vary greatly from year to year due to changes in weather patterns, such as drought or heavy rainfall. This variability makes it difficult to plan and manage irrigation using the basin system, as farmers cannot rely on a consistent and predictable supply of water. Additionally, the basin system may not be suitable for certain crops, and requires significant labor to construct and maintain. Overall, the unpredictability of the Nile's flow makes the basin system of irrigation less reliable than other methods of irrigation that do not rely on natural water sources.

Pregunta 9 Informe
Which of the following least influences the growth of settlements?
Detalles de la respuesta
The correct option is "Age" which least influences the growth of settlements. Age, as a factor, refers to the length of time a settlement has existed. However, the age of a settlement does not necessarily determine its growth or development. Instead, other factors such as climate, mineral resources, relief, and the presence of manufacturing industries play a more significant role in the growth of settlements. Climate affects agriculture and human habitation, mineral resources provide economic benefits, relief determines accessibility and land use, and manufacturing industries create employment and promote trade. Therefore, age is not as influential in the growth of settlements compared to these other factors.

Detalles de la respuesta
One important consequence of the location of Nigeria between latitudes 40 and 140 North of the equator is that some parts of the country enjoy a hot, wet, tropical climate throughout the year. This is because Nigeria is located within the tropical region of the earth, which is characterized by high temperatures and rainfall due to the direct overhead rays of the sun. The proximity of Nigeria to the equator also means that it receives a relatively equal amount of sunlight throughout the year, leading to a relatively stable climate in terms of temperature and rainfall. This is why some parts of the country, particularly the southern regions, experience hot, wet, and humid conditions throughout the year, which are favorable for the growth of vegetation and agriculture.

Detalles de la respuesta
The Muturu type of cattle is reared mainly in the western highland region of Nigeria because of its resistance to tsetse flies. Tsetse flies are insects that suck the blood of animals and spread diseases that can be fatal to them. The western highland region of Nigeria is known to have a high population of tsetse flies, making it unsuitable for rearing other types of cattle that are not resistant to them. However, the Muturu cattle are able to survive in this region because of their natural resistance to the flies, which makes them the most suitable breed for rearing in this area.

Detalles de la respuesta
A major characteristic of the local craft industry is that it is mainly hereditary. This means that the skills and knowledge required to produce these crafts are passed down from generation to generation within a particular community or family. It does not require a specially built factory, but can be produced in small workshops or even in homes. The craft industry also typically relies on a relatively small labor force, with each artisan or craftsman specializing in a particular aspect of the production process. The products of the craft industry are often sold locally or regionally, and may be used by other industries or businesses, but are primarily created for their own unique artistic or functional qualities. Finally, while the raw materials for craft production may be sourced locally, they can also be imported.

Detalles de la respuesta
Africa has the largest potential reserves of hydro-electric power in the world due to the abundant rainfall and waterfalls present in the continent. Many of the major rivers in Africa, such as the Congo, Zambezi, and Nile, have significant waterfalls that can be harnessed for hydro-electric power generation. Additionally, the rainfall in many regions of Africa is high, leading to the formation of large bodies of water and river systems that can also be used to generate hydro-electric power. Therefore, the combination of abundant water resources and waterfalls make Africa a prime location for the development of hydro-electric power, which can provide a reliable and renewable source of energy for the continent's growing population and economy.

Pregunta 20 Informe
Which of the following soils is easily water-logged?
Detalles de la respuesta
The type of soil that is easily waterlogged is clayey soil. Clayey soil has tiny particles with less pore spaces that can hold water, making it less permeable and prone to waterlogging. When it rains, water can't drain quickly through the soil, and it accumulates on the surface, which leads to the soil becoming waterlogged. This condition can cause damage to crops because the roots will not have access to oxygen, which is necessary for their survival. Therefore, clayey soil is not suitable for certain crops that can't withstand waterlogging.

Detalles de la respuesta
The green plants that serve as producers in the ecosystem are called autotrophs. Autotrophs are organisms that produce their own food using energy from the sun through the process of photosynthesis. These green plants convert light energy from the sun into chemical energy, which is stored in their tissues in the form of carbohydrates. Other organisms in the ecosystem, such as herbivores and carnivores, depend on these autotrophs for their food and energy, making them the primary producers in the food chain.
Pregunta 26 Informe
which of the following is a disadvantage of water transport?
Detalles de la respuesta
The disadvantage of water transport is that it is not flexible. This means that water transport schedules are not as frequent as those of road, rail or air transport. Water transport may have to wait for the goods to reach a certain amount or until the ship is full before it can leave the port. In addition, water transport is not as adaptable to changes in destination or sudden changes in the size and volume of goods being transported, as it can be costly to make changes to the ship's route or to transfer goods to another ship. Therefore, water transport may not be the best choice for businesses that require faster delivery times or greater flexibility in their shipping options.
