Show answer
Correct Option: B
Explanation:

Carbohydrates provide us with energy. Carbohydrates can be monosaccharides (composed of one monomer unit only like glucose, fructose etc.), disaccharide (composed of two monomer units like maltose which is made up of two units of glucose; sucrose made up of one unit of glucose and one unit of fructose) or polysaccharide (made up of multiple monomer units example starch which is composed of multiple units of glucose).

In mammals, carbohydrates are stored in the form of

  1. Lactic acid in muscles

  2. Glycogen in liver and muscles

  3. Glucose in liver and muscles

  4. Glycogen in liver and spleen

Show answer
Correct Option: B
Explanation:

Carbohydrates can be stored in body for subsequent use. Starch is an important storage polysaccharide in plants and glycogen is an important storage polysaccharide in animals. Both starch and glycogen are homopolymers of glucose.

  3. Nutrient guide

  4. Food guide tree

Show answer
Correct Option: B
Explanation:

The food guide pyramid is a pyramid-shaped guide of healthy foods divided into sections. Each section shows the recommended intake for each food group (i.e. Protein, Fat, Carbohydrates, and Sugars). Therefore, (b) is the correct answer.

Show answer
Correct Option: B
Explanation:

Fish flour is a source of amino acids and vitamin with very high protein content, made of fresh sea fish or unprocessed fish wastes. Due to its rich nutritional content, it is the most important material in the rations of barn animals, poultry and fish and is commonly used in the feed industry.


So, the correct option is 'Protein'.

  1. Histiocytes

  2. Mast cells

  3. Leukocytes

  4. All of the above

Show answer
Correct Option: C
Explanation:

The term wandering cell (or ameboid cell)[1] is used to describe cells that are found in connective tissue, but are not fixed in place. This term is used occasionally and usually refers to blood leukocytes (which are not fixed and organized in solid tissue) in particular mononuclear phagocytes.


So, the correct answer is 'Leukocytes'.
