What are fats and carbohydrates?

Directions: Read the passage given carefully and answer the question that follows.

The diet which contains adequate amount of all the important nutrients like carbohydrates, fats, proteins, minerals and vitamins, sufficient for the normal growth and development of the body is called a balanced diet. The constituents of balanced diet are - Carbohydrates, Fats, Proteins, Minerals (Salts), Vitamins, Water and Roughage, Carbohydrates are the compounds of carbon, hydrogen and oxygen. They are the main source of energy. The fats are the compounds of carbon, hydrogen and oxygen. The main function of fats in the body is to provide a steady source of energy. The proteins are highly complex organic compounds of carbon, hydrogen, oxygen and nitrogen. Proteins are very important for the growth and repair of the body. Kwashiorkor is a disease which occurs due to the deficiency of proteins in the diet of children whereas Marasmus occurs in the infants (small children) due to the deficiency of proteins. The metals, non-metals and their salts are called minerals. Our body needs minerals for its proper functioning.

  1. Compounds of carbon, hydrogen and oxygen

  2. Compounds of carbon and hydrogen

  3. Compounds of carbon and oxygen

  4. Compounds of carbon
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

 According to the passage, "Carbohydrates are the compounds of carbon, hydrogen and oxygen". So, option 1 is the correct answer.

Multiple choice

Which of the following factors is responsible for ill health of a person?

Thus, options (1), (3) and (4) help a person to be healthy as these habits keep the germs away and thus, reduce the chances of getting infected by diseases. But, drinking alcohol is not a healthy practice as it adversely affects the nervous system and its prolonged consumption adversely affects the liver and general body health. Thus, (2) is the correct answer because drinking alcohol is responsible for the ill health of a person.

A recent medical journal published a study, which found that athletes who exercised more than five hours per week were more likely than the other athletes to have high levels of chemical compound riboflavin in their blood. High levels of this compound can be one of the first warning signs of skin cancer, which is almost always caused by excessive exposure of the body to water.

Which one of the following, if true, would cast doubt on the study’s conclusion that exercising more than five hours per week increases the odds of contracting skin cancer?

  1. Lack of exercise increases the rate of absorption of many dangerous chemical compounds into the blood stream.

  2. Exercise increases the rate of blood flow through the circulatory system, thereby increasing the rate at which contaminants spread through the body.

  3. Majority of the athletes studied were swimmers.

  4. Athletes contract skin cancer at a significantly higher rate than common people do.
