  3. Antacids

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Dietary fiber is the indigestible portion of the carbohydrate in the food derived from plants. These are of two types - the soluble fiber and the insoluble one. The insoluble fiber is metabolically inert and being prebiotic and ferment in the large intestine. These bulking fibers tend to absorb water as they move through the digestive system which helps in easy defecation. Hence, consuming a diet with high fiber content will help prevent constipation.

Thus, the correct answer is option A.

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Proteins are the body building nutrients. Cell is the building block of our body. Most of the structures of the cells are formed with protein. Without protein no cell can be formed and be functional. So, proteins are called the body building nutrients.

Which one is not a source of carbohydrates?

  1. Wheat

  2. Gram

  3. Rice

  4. Sorghum
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The chickpea or chick pea is a legume of the family Fabaceae, subfamily Faboideae. It is also known as gram, or Bengal gram, garbanzo or garbanzo bean, and sometimes known as Egyptian pea, ceci, cece or chana, or Kabuli chana. It is the major source of proteins and not of carbohydrates. Wheat, rice and sorghum are the sources of carbohydrates. Thus, the correct answer is option B.

Which of the following are energy giving foods?

  1. Groundnut and eggs

  2. Eggs and milk

  3. Soybean and groundnut

  4. Potatoes and rice
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Human food should consist of a variety of nutrients such as carbohydrates, minerals, fats, proteins, vitamins and fibre. However, carbohydrates provides the human body with maximum energy. Carbohydrates are broken down to various forms of glucose which acts as the best source of energy. A diet rich in carbohydrates includes potatoes, both white and sweet and rice (mainly brown rice) and foods made from whole wheat.

  2. Cooked Food

  3. Air

  4. Coffee
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Natural resources are materials provided by the earth that humans can use to make more complex (human-made) products.

If we use a product directly as obtained from nature, they are termed as natural resources
Tea is not a natural resource but tea leaves are natural resources.
Cooked food is not a natural resource but raw food are natural resources.
Coffee beans are a natural resource, coffee is not natural resources.
Air, on the other hand, is available to us naturally and hence, is a natural resource.

Multiple choice botany biotechnology and its applications biotechnology in agriculture gm crops transgenic organisms

The improved trait in golden rice is

  1. High glysine content

  2. High protein content

  3. Insect resistance

  4. High vitamin A content
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Golden rice is a variety of rice (Oryza sativa) produced through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, in the edible parts of rice. The research was conducted with the goal of producing a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A, a deficiency which is estimated to kill 670,000 children under the age of 5 each year.
Golden rice differs from its parental strain by the addition of three beta-carotene biosynthesis genes.

If a person is kept on food with almost no carbohydrates, the first stored source of energy provided by the body is 

  1. Proteins

  2. Fats

  3. Glycogen

  4. Salts
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The glucose stored in the liver serves as a buffer for blood glucose levels. Therefore, if the blood glucose levels start to get low because person has not consumed food for a period of time, the liver is able to release glucose into the bloodstream to maintain healthy levels. If the body reserves of glucose deplete, a process called gluconeogenesis will take place. During gluconeogenesis, glucose is synthesized from molecules that are not carbohydrates.
