Which one is not a Local Self Government?
A)
Panchayati Raj Institution
B)
Municipal Council
C)
Municipal Corporation
D)
Autonomous District Council
Local Self Government (LSG) in India refers to the management of local affairs by elected representatives of the local people. It is broadly divided into two categories: Rural Local Government (Panchayati Raj Institutions) and Urban Local Government (Municipalities).
1. Panchayati Raj Institutions (Option a) are the constitutional bodies for rural local self-government (Part IX of the Constitution).
2. Municipal Councils (Option b) and Municipal Corporations (Option c) are the constitutional bodies for urban local self-government (Part IXA of the Constitution).
In contrast, Autonomous District Councils (ADCs) are established under the Sixth Schedule of the Indian Constitution to provide autonomy to tribal areas in certain North-Eastern states (Assam, Meghalaya, Tripura, and Mizoram). While they perform some local administrative functions, they are specialized constitutional bodies designed for ethnic/tribal autonomy and legislative powers within a district, rather than being standard 'Local Self Government' units like the Panchayats or Municipalities which apply across the general administrative framework of the country.

Indian constitution does not provide any procedure to remove the
A)
President
B)
Vice President
C)
Governor
D)
Judge of Supreme Court
The Indian Constitution provides specific mechanisms for the removal of various high-ranking officials, but the Governor's position is unique.
1. **President (Option a):** The Constitution provides a detailed procedure for the removal of the President through a process called 'Impeachment' under Article 61, based on the grounds of 'violation of the Constitution'.
2. **Vice President (Option b):** The Vice President can be removed by a resolution of the Rajya Sabha passed by an effective majority and agreed to by the Lok Sabha (Article 67).
3. **Judge of Supreme Court (Option d):** Judges of the Supreme Court can be removed by the President on the recommendation of Parliament after an address is passed by both houses with a special majority on grounds of 'proved misbehaviour or incapacity' (Article 124(4)).
4. **Governor (Option c):** The Constitution does not lay down any specific procedure or grounds for the removal of a Governor. According to Article 156, the Governor holds office during the 'pleasure of the President'. This means the President (acting on the advice of the Union Council of Ministers) can remove a Governor at any time without providing a reason or following a formal removal process.
The tree on which Mizo warriors hung the decapitated heads of their enemies
A)
Sahlam
B)
Thinglu
C)
Seluphan
D)
Thingsia
In traditional Mizo culture, headhunting was practiced by warriors to prove their bravery and bring honor to their village. The 'Thingsia' was a specifically designated tree (often a sturdy, prominent tree) used as a trophy rack where the decapitated heads of enemies were hung to display the warrior's success and the village's strength.
Analysis of other options:
- Sahlam: Refers to a specific type of traditional Mizo attire or ornament, not a tree.
- Thinglu: Generally refers to a wooden drum or a specific type of wooden implement.
- Seluphan: Not a recognized term for a trophy tree in Mizo historical records.
Therefore, 'Thingsia' is the correct term for the tree used for this purpose.
Inability of clotting of blood is due to the deficiency of
A)
Vitamin A
B)
Vitamin B1
C)
Vitamin D
D)
Vitamin K
Blood clotting (coagulation) is a complex process that requires several clotting factors. Vitamin K is a fat-soluble vitamin that acts as a necessary cofactor for the enzyme gamma-glutamyl carboxylase. This enzyme is essential for the synthesis of several key clotting factors in the liver, specifically Factors II (prothrombin), VII, IX, and X. Without sufficient Vitamin K, these proteins cannot be activated, leading to a failure in the coagulation cascade and resulting in the inability of blood to clot, which increases the risk of excessive bleeding (hemorrhage).
Why other options are incorrect:
- Vitamin A: Primarily involved in vision, immune function, and skin health. Deficiency leads to night blindness.
- Vitamin B1 (Thiamine): Essential for glucose metabolism and nerve function. Deficiency leads to Beriberi.
- Vitamin D: Essential for calcium absorption and bone mineralization. Deficiency leads to Rickets in children and Osteomalacia in adults.
The isotope of carbon used in radiocarbon dating is
A)
C-12
B)
C-13
C)
C-14
D)
C-15
Radiocarbon dating is a method used to determine the age of organic materials by measuring the amount of Carbon-14 (C-14) remaining in a sample.
1. **Carbon-14 (C-14)** is a radioactive isotope of carbon. It is produced in the upper atmosphere by cosmic rays and is absorbed by living organisms (plants via photosynthesis and animals via the food chain) in a constant ratio relative to stable carbon.
2. **The Process**: Once an organism dies, it stops absorbing carbon. The C-14 already present in the tissues begins to decay into Nitrogen-14 at a known, constant rate (its half-life is approximately 5,730 years).
3. **Dating**: By measuring the remaining C-14 concentration and comparing it to the initial atmospheric concentration, scientists can calculate how long ago the organism died.
**Why other options are incorrect:**
- **C-12 (Option a)**: This is the most common and stable isotope of carbon. It does not decay, so it cannot be used as a 'clock' for dating.
- **C-13 (Option b)**: This is also a stable isotope of carbon. While used in other types of chemical analysis (like tracing metabolic pathways), it is not radioactive and cannot be used for radiocarbon dating.
- **C-15 (Option d)**: This is a very short-lived radioactive isotope with a half-life of only a few seconds, making it useless for dating archaeological or geological samples.
