B Correct answer
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

B Correct answer
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.

  1. Flow chart

  2. Food guide pyramid

  3. Nutrient guide

  4. Food guide tree
Reveal answer Fill a bubble to check yourself
B Correct answer
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.

Fish flour is rich in

  1. Fat

  2. Protein

  3. Vitamins

  4. Minerals
Reveal answer Fill a bubble to check yourself
B Correct answer
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. Carbohydrates, fats, proteins

  2. Fats, carbohydrates, proteins

  3. Carbohydrates, proteins, lipids

  4. Proteins, lipids, carbohydrates
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

During fasting, the body first utilizes glycogen (carbohydrates) for energy, followed by stored fats (lipids), and finally breaks down proteins (muscle tissue) as a last resort.

Wandering cells are

  1. Histiocytes

  2. Mast cells

  3. Leukocytes

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
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'.

Multiple choice evs sources of water conservation of natural and energy resources energy conservation and sources reduce, recycle, reuse importance of the conservation of natural resources

How much radiant energy will an object emit if its temperature is at absolute zero?

  1. The maximum theoretical amount

  2. None

  3. The same as it would at any other temperature

  4. Depends on the chemical composition of the object
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

According to the third law of thermodynamics, at absolute zero, all molecular motion ceases, and therefore an object emits no radiant energy (thermal radiation).

  1. Recycling

  2. Use for repurpose

  3. Reduce the use

  4. Refuse the use
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The waste management hierarchy emphasizes the 3Rs: Reduce, Reuse, and Recycle. If reusing an envelope is a management method, reducing the consumption of fuel is the corresponding conservation strategy.
