The gums hold our teeth in place. They are the soft tissue that surrounds the base of our teeth and provides support and stability. Without healthy gums, our teeth would become loose and eventually fall out. The gums also protect the roots of our teeth and help to keep them clean by creating a seal around them. Therefore, the correct answer is gums.

Sitting in the sun for 15-20 minutes a day provides you with vitamin D. The sun is a natural source of vitamin D, and exposure to sunlight triggers the production of this essential vitamin in our bodies. Spending time in the sun allows our skin to absorb UVB rays, which convert a form of cholesterol in our skin into vitamin D. Therefore, sitting in the sun is a simple and effective way to ensure adequate vitamin D levels in our body.

Food is necessary for all living things to survive and sustain their bodily functions. It provides the essential nutrients, vitamins, and energy required for growth, development, and maintenance of the body. Without food, living organisms would not be able to carry out their biological processes and would eventually die.

The first teeth of a child are called milk teeth. These teeth are also known as deciduous teeth or primary teeth. They start to erupt around the age of 6 months and eventually fall out to make way for the permanent teeth. The term "milk teeth" is commonly used because these teeth are whiter and resemble milk in color. They are temporary and will be replaced by the permanent teeth as the child grows.

Roughage cannot be digested in our body because it is a type of dietary fiber that is not broken down by our digestive enzymes. Instead, it passes through our digestive system largely intact, adding bulk to our stool and aiding in regular bowel movements. It helps in preventing constipation and maintaining a healthy digestive system.

All of the listed options contain sugar. Chocolates, fruits, and candy are known to have varying amounts of sugar content. Chocolates and candy are typically high in added sugars, while fruits naturally contain sugars. Therefore, all of these options are correct in terms of containing sugar.

A balanced diet contains all of these components - carbohydrates, proteins, and fats. Carbohydrates are the main source of energy for the body, while proteins are essential for growth, repair, and maintenance of tissues. Fats provide energy, help absorb vitamins, and protect organs. Including all three in the diet ensures that the body receives a variety of nutrients necessary for overall health and well-being.

Oranges are a good source of vitamin C. Vitamin C is an essential nutrient that helps support the immune system, promotes healthy skin, and aids in the absorption of iron. Oranges are particularly known for their high vitamin C content, making them a popular choice for boosting immune health and overall well-being.

Before the American Revolution, most American colonists earned a living by farming. This was due to the fact that agriculture was the main economic activity in the colonies, and farming provided a reliable source of sustenance and income for the colonists. The fertile land in the colonies allowed for the cultivation of crops such as corn, wheat, and tobacco, which were in high demand both locally and in Europe. Additionally, farming also involved the rearing of livestock, which provided food and materials like wool and leather. Overall, farming was the primary occupation for the majority of American colonists during this period.

If a person does not get food for a long time, they are likely to feel both tired and weak. The lack of food deprives the body of necessary nutrients and energy, leading to fatigue and a decrease in physical strength.

Calcium-rich foods are good for your teeth because calcium is an essential mineral that helps to strengthen and protect tooth enamel. Tooth enamel is the outer layer of the tooth that acts as a protective barrier against bacteria and acid. When the enamel is weak or damaged, it can lead to tooth decay and cavities. Calcium helps to remineralize and strengthen the enamel, making it more resistant to decay and erosion. Therefore, consuming foods high in calcium, such as dairy products, leafy greens, and fortified foods, can contribute to better oral health and stronger teeth.

After the Civil War, African-American slaves gained their freedom. The Emancipation Proclamation, issued by President Abraham Lincoln in 1863, declared that all slaves in Confederate territory were to be set free. This marked a significant change for African-Americans in the South, as they were no longer considered property and were granted basic rights and freedoms. However, it is important to note that while the end of slavery was a major milestone, African-Americans still faced significant challenges and discrimination in the years that followed.

Foods rich in carbohydrates provide energy to the body. Carbohydrates are broken down into glucose, which is the primary source of fuel for our cells. Therefore, it is correct to say that foods rich in carbohydrates are called "energy-giving foods".

Glucose is the correct answer because it is a simple sugar that is quickly absorbed into the bloodstream, providing a rapid source of energy for the body. Unlike pizza or samosa, which are high in carbohydrates and fats and take longer to digest, glucose is readily available and can be used by the body immediately. Therefore, consuming glucose can give you a quick boost of energy.

During the American Revolution, many colonial women played a crucial role in keeping the farms and shops running. With the men away fighting, women took on the responsibility of managing and maintaining the agricultural and commercial activities that were essential for the survival of their communities. They worked tirelessly to ensure that food was produced and distributed, and that goods and supplies were available. Their contribution in sustaining the economy during the war was vital and allowed the revolutionaries to continue their fight against the British.

Proteins are considered as body building food because they play a crucial role in the growth and repair of tissues in our body. They are responsible for building and maintaining muscles, bones, and other body structures. Proteins are made up of amino acids, which are the building blocks of our body. They are essential for the development and maintenance of a healthy body. While proteins do provide energy, their primary function is to support the growth and maintenance of the body's tissues, making the answer "body building" the correct choice.

Obesity leads to heart diseases. Obesity is a condition characterized by excessive body fat, which can lead to various health complications. One of the most common and serious consequences of obesity is the increased risk of developing heart diseases. Excess weight puts strain on the heart, leading to conditions like high blood pressure, coronary artery disease, and heart failure. Therefore, the correct answer is "heart."

Canines are the teeth that are used for tearing food like meat. They have long and pointed crowns, which are ideal for gripping and tearing apart tough food. Canines are located at the corners of the mouth and are well-suited for their role in tearing and shredding meat before it is further chewed by the molars and premolars for digestion. Incisors are used for biting and cutting, premolars are used for grinding, and molars are used for crushing and grinding food.

Fungi is the correct answer because fungi are known to grow on dead plants and animals as well as on rotten food. Fungi are decomposers and play a crucial role in breaking down organic matter, such as dead plants and animals, into simpler compounds. They obtain nutrients from these decomposed materials, making them well-suited for growing on dead organisms and decaying food.

The main reason the Pilgrims wanted to leave England was to escape bad treatment because of their religion. They were seeking religious freedom and wanted to practice their own beliefs without persecution. England at the time had a state church and those who did not conform to its teachings faced discrimination and punishment. The Pilgrims believed that they could find a new home where they could freely worship and live according to their own religious convictions.

Many historians believe that the ancestors of American Indians came from the continent of Asia. This is supported by archaeological evidence, genetic studies, and linguistic similarities between Native American languages and those spoken in Asia. The theory is that these ancestors migrated across the Bering land bridge, which connected Asia and North America during the last Ice Age. This migration is believed to have occurred around 15,000 years ago, making Asia the most likely continent of origin for the ancestors of American Indians.

Children need more proteins than adults because protein is essential for their growth and development. Proteins are the building blocks of the body and are necessary for the formation of muscles, bones, and tissues. During childhood, children experience rapid growth, and their bodies require a higher amount of protein to support this growth. Additionally, proteins are also important for the proper functioning of the immune system and the production of enzymes and hormones. Therefore, children need a higher intake of proteins compared to adults.

Molars, located at the back of the mouth, are broad, flat teeth with multiple cusps designed for grinding and crushing food. Their strong and sturdy structure allows them to effectively break down food into smaller particles, facilitating digestion and nutrient absorption in the digestive system.

The innermost portion of the tooth is called the pulp. The pulp is a soft tissue that contains blood vessels, nerves, and connective tissue. It is located in the center of the tooth, within the pulp chamber and root canal. The pulp plays a vital role in nourishing the tooth and transmitting sensory information such as pain and temperature.

Enamel is the hardest substance in the human body. It is a protective layer that covers the outer surface of teeth, providing strength and durability. Enamel is composed of minerals, mainly hydroxyapatite, which makes it highly resistant to wear and tear. It helps to protect the teeth from damage caused by chewing, biting, and other daily activities. Enamel is even harder than bone and nails, making it the correct answer.
