C. Proteins

Explanation
Proteins are essential nutrients that play a crucial role in bodybuilding. They are responsible for repairing and building muscle tissues, as well as aiding in the growth and development of muscles. Proteins also help in the synthesis of enzymes, hormones, and antibodies, which are important for overall body function and immune system health.

Therefore, consuming an adequate amount of protein is necessary for individuals looking to build and maintain muscle mass.

- C.
  
  Carnivore
- D.

Correct Answer
A. Herbivore

Explanation
The correct answer is "Herbivore" because a herbivore is an animal that only eats plant products. Deer fall into this category as they primarily consume grass, leaves, and other vegetation. They do not eat meat or insects, which are characteristic of carnivores and insectivores respectively. Additionally, deer do not consume a combination of plant and animal products, which would classify them as omnivores. Lastly, the term "cannibal" refers to an animal that eats its own species, which is not applicable to deer.

Explanation
The correct answer is stem. The stem is the part of the plant that connects the roots to the leaves and flowers. It provides support to the plant and transports water, nutrients, and sugars between the roots and leaves. In the case of a potato, the edible part is an underground stem called a tuber.

B. Iodine

Explanation
Iodine is used to test carbohydrates because it reacts with carbohydrates to form a blue-black color. This reaction is known as the iodine test and is commonly used to detect the presence of starch in a substance. When iodine is added to a solution containing carbohydrates, such as starch, it will turn from a yellow-brown color to a blue-black color if carbohydrates are present. Therefore, iodine is the solution used to test for carbohydrates.

  Butterfly
- B.
  
  Bees
- C.
  
  House fly
- D.
  
  Mosquito
- E.
  
  All of the above
Correct Answer
B. Bees

Explanation
Bees are the organisms that convert nectar to honey. Bees collect nectar from flowers using their long tongues and store it in their honey stomachs. Enzymes in their stomachs break down the complex sugars in the nectar into simpler sugars. When the bees return to the hive, they regurgitate the nectar and other bees in the hive further break it down and evaporate the excess moisture, resulting in the formation of honey. Bees then store the honey in honeycombs for future use as a food source.

  Vitamin-D
- C.
  
  Vitamin-c
- D.
  
  Vitamin-B
- E.
  
  Vitamin-E
Correct Answer
B. Vitamin-D

Explanation
Rickets is caused due to a deficiency of Vitamin-D. Vitamin-D plays a crucial role in the absorption of calcium and phosphorus in the body, which are essential for the development and strengthening of bones. A deficiency of Vitamin-D can lead to impaired bone growth and mineralization, resulting in rickets. This condition is characterized by weak and soft bones, delayed growth, skeletal deformities, and muscle weakness. Therefore, ensuring an adequate intake of Vitamin-D is crucial for the prevention and treatment of rickets.

  Goiter
- B.
  
  Anaemia
- C.
  
  Loss of vision
- D.
  
  Beri beri
- E.
  
  Scurvy
Correct Answer
B. Anaemia

Explanation
Anaemia is a disease caused due to deficiency of iron. Iron is an essential component of hemoglobin, which carries oxygen to the body's tissues. When there is a lack of iron, the body is unable to produce enough healthy red blood cells, leading to a decrease in the oxygen-carrying capacity of the blood. This can result in symptoms such as fatigue, weakness, shortness of breath, and pale skin. Therefore, anaemia is the correct answer as it directly relates to the deficiency of iron.

Sprouts are small white structures that grow from soaked seeds. When seeds are soaked in water, they begin to germinate and sprout. Sprouting is the process where a seed starts to grow and develop into a young plant. The sprouts usually have a small white stem with tiny leaves or shoots emerging from it. They are commonly eaten as a nutritious addition to salads, sandwiches, and other dishes. Therefore, the correct answer for the given question is "Sprouts".

This broad diet allows them to obtain nutrients from both plant and animal sources, making them adaptable to different environments and increasing their chances of survival.
