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.

Which organism convert nectar to honey?( )

Butterfly
Bees
House fly
Mosquito
All of the above

Correct Answer

A. 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-A
Vitamin-D

Vitamin-B
Vitamin-E

Correct Answer

A. 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.

Name the disease caused due to deficiency of Iron?( )

Goiter
Anaemia
Loss of vision
Beri beri
Scurvy

Correct Answer

A. 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.
