A General Knowledge Quiz For 5th Graders!

Plants grow out of seeds. Seeds contain the necessary nutrients and genetic information for a plant to develop and grow. When a seed is planted in soil and provided with water, it germinates and begins to grow roots, stems, and leaves. Therefore, the correct answer is "Seed".

Butter is the correct answer because it is a dairy product that is made from churning cream or milk. It is known to be high in fat content, with approximately 80% of its composition being fat.

Milk is the correct answer because it is a well-known source of calcium. Calcium is an essential mineral for the development and maintenance of strong bones and teeth. It is also important for proper muscle function and nerve transmission. While honey, sugar, and potato do not contain significant amounts of calcium, milk is a rich source of this nutrient, making it an important part of a balanced diet for individuals looking to meet their calcium requirements.

Germination refers to the process in which a seed develops into a seedling. It involves the activation of the embryo within the seed, leading to the emergence of a root and shoot. During germination, the seed absorbs water and essential nutrients from the soil, triggering metabolic activities and growth. This process is crucial for the establishment and growth of new plants.

Agriculture refers to the practice of growing plants on a large scale. It involves cultivating crops, raising livestock, and other activities related to farming. Agriculture is essential for food production and plays a crucial role in the economy of many countries.

Sweet potatoes are a type of root vegetable, which means they grow underground. The edible part of the sweet potato is the root, which is typically large and tuberous. The roots of the sweet potato plant store nutrients and sugars, making them the part of the plant that is harvested and consumed. Therefore, the correct answer is roots.

Covid 19 is a communicable disease because it is caused by a virus called SARS-CoV-2 that can be transmitted from person to person through respiratory droplets when an infected person coughs, sneezes, or talks. It spreads easily in close contact situations and can also be transmitted by touching surfaces contaminated with the virus and then touching the face. Heart attack and lung disease, on the other hand, are not communicable diseases as they are caused by non-infectious factors such as lifestyle choices, genetics, or environmental factors.

Russia is the largest country in the world by land area, covering over 17 million square kilometers. It spans Eastern Europe and northern Asia, making it nearly twice the size of the second-largest country, Canada. While China, Canada, and the United States are also large countries, they do not surpass Russia in terms of total land area.

Plants that grow from stem cuttings include rose and sugarcane. Stem cuttings are a method of asexual reproduction in plants, where a portion of the stem is cut and planted in soil or water. The cut stem develops roots and eventually grows into a new plant. Rose and sugarcane are examples of plants that can easily propagate through stem cuttings, making it a common method for their cultivation.

The symptoms of the coronavirus include fever, cough, cold, and loss of taste and smell. These symptoms are commonly observed in individuals infected with the virus. Fever is a common symptom and is often one of the first signs of infection. Cough and cold symptoms are also prevalent, with individuals experiencing a persistent cough and nasal congestion. Additionally, loss of taste and smell has been identified as a distinct symptom of COVID-19. Therefore, all of these symptoms are associated with the coronavirus.

Tribal people get their food from both trees and by hunting animals. They gather fruits, nuts, and other edible plants from trees, while also relying on hunting animals for meat. This combination of gathering food from nature and hunting ensures their survival and sustenance.

Roses can be grown from stems. This is because roses can be propagated through a process called stem cuttings, where a stem is cut from a mature rose plant and planted in soil or water. The stem then develops roots and eventually grows into a new rose plant.

All of these food items provide energy because they contain carbohydrates, which are the body's main source of fuel. Rice, sugar, and bread are all rich in carbohydrates and can be broken down into glucose, which is used by the body for energy. Therefore, consuming any of these food items can provide the necessary energy for the body's daily functions and activities.

Anaemia is a disease caused by a deficiency of iron. Iron is necessary for the production of hemoglobin, a protein in red blood cells that carries oxygen throughout the body. When there is a lack of iron, the body is unable to produce enough healthy red blood cells, leading to symptoms such as fatigue, weakness, and pale skin. Therefore, anaemia is the correct answer for the disease caused by iron deficiency.

Corn is the correct answer because it is a good source of dietary fiber, also known as roughage. Roughage refers to the indigestible parts of plant-based foods that add bulk to the diet and help regulate bowel movements. Corn contains both soluble and insoluble fiber, which can aid in digestion, promote a feeling of fullness, and support a healthy digestive system. Eggs, fish, and milk do not contain significant amounts of roughage.

Prevention is better than cure because it focuses on avoiding or minimizing the occurrence of a problem or illness before it happens. By taking preventive measures such as maintaining a healthy lifestyle, practicing good hygiene, and getting regular check-ups, individuals can reduce the risk of developing diseases or conditions. Prevention also helps to save time, money, and resources that would otherwise be spent on treating and managing illnesses. It emphasizes the importance of proactive measures to maintain overall well-being and avoid the need for medical intervention.

Beriberi is a disease that is caused by a deficiency of vitamin B1, also known as thiamine. This vitamin plays a crucial role in the metabolism of carbohydrates, and its deficiency can lead to symptoms such as muscle weakness, fatigue, nerve damage, and cardiovascular problems. Beriberi is commonly found in populations that consume a diet mainly consisting of polished rice, as the milling process removes the outer layer of the grain, which is where thiamine is primarily found. Therefore, the correct answer is Beriberi.

Rickets is a non-communicable disease characterized by a deficiency in vitamin D, calcium, or phosphate. It affects bone development in children, leading to weakened and soft bones. Unlike typhoid, chicken pox, and the common cold, rickets is not caused by a bacterial or viral infection and cannot be transmitted from person to person.

Wind, water, and animals play a crucial role in the dispersal of seeds and spores. They help in carrying the seeds or spores away from the parent plant to new locations where they can germinate and grow into new plants. This process of dispersal increases the chances of survival for the seeds and spores as it allows them to spread out and colonize different areas. Therefore, the correct answer is dispersal.

The first case of Covid-19 was identified in Wuhan. Wuhan, located in China, is widely recognized as the epicenter of the initial outbreak of the virus. The identification of the first case in Wuhan marked the beginning of the global pandemic that has since spread to various countries around the world.
