Scurvy is caused due to deficiency of:
To solve the problem, we need to identify the cause of scurvy, specifically which nutrient deficiency leads to this condition.
1. Understanding Scurvy:
Scurvy is a disease historically associated with sailors and others deprived of fresh fruits and vegetables for extended periods. It is characterized by symptoms such as bleeding gums, poor wound healing, and fatigue.
2. Identifying the Deficiency:
Scurvy is caused by a deficiency of Vitamin C (ascorbic acid), a water-soluble vitamin essential for collagen synthesis, antioxidant functions, and connective tissue health. Lack of Vitamin C disrupts these processes, leading to the symptoms of scurvy.
3. Considering Other Possibilities:
Other vitamin deficiencies cause distinct diseases (e.g., Vitamin D deficiency causes rickets, Vitamin B1 deficiency causes beriberi). No other nutrient deficiency is associated with scurvy, confirming Vitamin C as the correct answer.
Final Answer:
Scurvy is caused due to the deficiency of Vitamin C.

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
